This program is designed to standardize and
coordinate amateur observations of meteoroid impacts on the Moon. This field
has exciting possibilities but only if the observations are done in a uniform
manner and pooled to look for confirmations of positive observations. Anyone
interested in participating should contact the Coordinator above for further
information. The Coordinator maintains an "Impact"
e-mailing list of regular participants, e-mail him if you would like

Links to Lunar Impact
Monthly Briefings and Opportunities to
Observe Lunar Meteors
For the ongoing monthly routine observations, the defined
start is set at three days after New Moon until two days after First Quarter
for the first half. The second half resumes two days before Last Quarter and
continues until three days before New Moon. The actual duration of each
observing interval will vary due to ecliptic angle, lunar elongation, and
observer latitude. I am posting these plans on a quarterly basis, which
provides, at a glance, the observing schedule along with any meteor showers
active during the observing windows. In general the observations fall into
three groups: evening, from three days after New Moon (NM) to two days after
First Quarter (FQ); morning, from two days prior to Last Quarter (LQ) to three
days prior to New Moon (NM); and significant shower, when the moon is favorably
placed (usually during these two intervals) during annual showers (whose names
will appear in bold type) with ground-based ZHR’s of 20 or more.
We are wrapping up the evening phase of the current
campaign as of this writing. When the moon reaches last quarter, the annual Perseid meteor shower will be starting to ramp up to its
August 12 maximum and will provide a source for lunar meteoroid impacts through
much of August.
Interval: 2 – 8 August (LQ = 4 August;
NM = 11 August), morning; the annual Perseid meteor
shower is active during this time, but at a much reduced rate during the time
of favorable moon configuration (Perseid peak is
August 12); the kappa Cygnids add a weak background
to the shower activity for most of August
Interval: 14 – 20 August (NM = 11
April; FQ = 18 August), evening; The waning Perseids and the kappa Cygnids
(peak August 18, ZHR = 3) are active during this time.
Interval: 1 – 6 September (LQ = 3 September;
NM = 9 September.), morning; the Aurigids are active
with their peak on September 1, ZHR = 6.
Interval: 12 – 18 September (NM = 9 September;
FQ = 16 September), evening; the southern Taurids start to pick up along with
the September epsilon Perseids.
Interval: 30 September – 6 October (LQ = 2 October;
NM = 9 October), morning; the only activity is from the Southern Taurids.
Interval: 12 – 18 October (NM = 9
October; FQ = 16 October), evening; the Southern Taurids, the Orionids (ramping
up to an October 21 peak, ZHR = 15), delta-Aurigids
and epsilon-Geminids are weakly active during this time.
Looking ahead, the moon is just past First Quarter when the
Leonids peak on November 17; and the Moon
is a waxing crescent just short of First Quarter during the
December 14 peak of the Geminids. These are events to be ready for,
especially the Geminids. As always, check back often for any updates on
activity related to these two major showers as well as any other developments.

Two Lunar Quadrantid
Candidates Videotaped (January 2017)
During the annual Quadrantid
meteor shower the moon was favorably placed for observation of lunar meteors.
The Swiss-Italian team of astronomers caught two events, highlighted below. If
anyone in Europe happened to be videotaping at the time please check your
videos at the indicated times below for signs of impact flashes. I plan to post
the images at the mirror site above on 19 January.
2017 January 1 at 17:47:15 UT, lasted 2 integration fields
(40 ms), imaged with one telescope.
2017 January 3 at 19:18:41 UT, lasted 4 integration fields
(80 ms), imaged with two telescopes.
Runs were performed from Rome (Italy), Gordola
and Locarno (Switzerland).
Reports of Lunar Meteors - 2015
The Swiss-Italian lunar meteor monitoring group, consisting
of observers Rafaello Lena, Stefano Sposetti and Marco Iten, reports
the observations of several impact flashes, each of which was confirmed by Dr.
J.M. Madiedo’s team. These events are summarized in
the below table and were observed in Europe when the Moon was below the horizon
for North America. However anyone monitoring the moon from North America with
video and at least an 8-inch telescope had a good chance of observing impacts
from the Northern Taurid meteor stream. The North Taurids are noted as being
the very likely source of the impact that was the first of over 300 events to
be observed by the Meteoroid Environment team at NASA-Marshall Space Flight
Center ten years ago.
The four flash detected by Stefano have

work and for reporting these results.
Other News and Developments
Videotaped in Jupiter’s Atmosphere
One of the ancillary activities of this section is to
observe meteors on other planets. Jupiter has historically provided the richest
field for such observations as seen from Earth’s surface. We encourage video
patrols of Jupiter on a regular basis to monitor the planet for meteors. It
would be useful scientifically to obtain a census of such objects and their
frequency of impact on Jupiter. The monitoring of meteors on Jupiter (and all
other solar system objects) will fall under the domain of the LMIS and I will
share more on this new venture by early 2018. One thing is certain…once we get
our observatory established at Prairie View A&M University in Texas, one of
the first projects I have in mind for the Meade 16-inch is regular monitoring
of Jupiter for meteor impacts and I will certainly need help from interested
and well-equipped observers from this Section.
On May 26th 2017 between 19:24.6 and 19:26.2 UT Sauveur Pedranghelu videotaped an
impact flash in Jupiter’s north polar region. The
flash lasted about 0.7 seconds and displayed two peaks in brightness. The
impact occurred at latitude 51 N and central meridian longitudes: System I = 74
deg.; System II = 159 deg.; and System III = 292 deg. More information about
this observation along with an image can be viewed at this website: http://www.skyandtelescope.com/astronomy-news/new-impact-flash-seen-at-jupiter/
with Plume made by Marco Iten and reported by Stefano
Sposetti, Marco Iten and Rafaello Lena:
Marco Iten detected an interesting luminous
event most probably generated by a meteoroidal impact on the Moon occurred
the 26 February 2015. The
position of the flash was along the terminator. The brightness of the
flash 0.16 s after the initial detection was +8.0 magV.
After the main lightdrop a successive residual
diffuse light lasted for several seconds.
Under the assumption of a meteoroidal impact, we argue that this
post luminous event and its ever growing dimensions was likely caused by
sunlight reflection on ejected materials released by the impact. Marco Iten detected it visually using no dedicated searching

video was shown to impact expert H. Jay Melosh of
Purdue University (USA) and he agrees that this appears to be a genuine impact
event, with the ejection of dust that is made visible as it rises into
sunlight. He suggested making measurements to find the height of the dust cloud.

general interest visual astronomy book (revised and corrected) entitled “The Art and Science of Visual
Astronomy”, is available for free
download. This is where I share my fascination with the aesthetic, visual side
of astronomy and include information on some of the best objects that amateur
astronomers look at on a regular basis. This is meant to instill interest in
visual astronomy as well as keep beginning astronomers hooked and interested in
observing. I cover a wide range, from the natural beauty of the Earth and daytime
sky, to the uniqueness of deep sky objects such as galaxies. A unique feature
of this free e-book are the tables of “equivalent distances” to objects of
various types (both within the local solar system and beyond), that is how
close one would be to a given object of interest to get a naked eye view that
matches what one sees through the eyepiece. Suggestions are always welcome for
improvement. The e-book can be downloaded from here. Please be aware that, because of all the pretty pictures,
it may take a few minutes to download completely. Once it is downloaded, you
can save a copy to your local machine.
Older Reports Related to Lunar
If you happened to have made observations of
the moon during the LADEE mission (November 2013 through April 2014) in search
of lunar meteors, but have not yet submitted your observations please do so as
soon as possible. Even if you have not looked over/analyzed your media for
events, send it to me and I can get it looked at. Although the LADEE mission is
now history (it crash-landed on the far side of the moon over a year ago, on
April 17, 2014), observations of lunar meteors are still needed. The complete
observing plan for lunar meteors in general for 2015 can be obtained here. The mirror site that complements
this site is online and will display images obtained by observers as soon as
they are received, to give near-real time updates of observers’ results. Also
included will be any information provided by the observer such as date, time,
location, etc. The mirror is part of the “Cosmic Corner” website at http://www.pvamu.edu/physics/cosmic-corner/.
Brian Day of NASA-Ames Research Center wrote:
“The Lunar Meteoroid Impacts and the LADEE mission online workshop was held on
Dec 5, 2013. Presenters included RickElphic (LADEE Project Scientist), Brian Cudnik (Coordinator of the ALPO Lunar
Meteoritic Impact Search, Author of “Lunar Meteoroid Impacts and How to Observe
Them), Rob Suggs (NASA Meteoroid Environment Office),
George Varros (pioneering observer of lunar
meteoroid impacts and author of “Nudger” lunar
auto-guider software), and PeterGural (author of LunarScan impact detection software). Because of
our international audience, the workshop was recorded and archived for
convenient viewing. You can view the workshop at http://connect.arc.nasa.gov/p4zpsnm6weh/.”
I highly recommend visiting this site and
watching the entire conference. Even though the mission has ended, there are
plenty of resources to help one get oriented to the observations of lunar
meteors. More information about the LADEE mission itself can be obtained from http://www.nasa.gov/mission_pages/LADEE/main/.
One of the main objectives for ground-based
observations was to correlate the occurrence of impact events with changes in
the dust concentration as measured by LADEE. This, combined with careful
measurements of the maximum intensity of the flash, its light curve, and knowing
the impact velocity of the meteoroid, should enable us to get an estimate of
the luminous efficiency (how much impact energy goes into making the optical
flash) of the impact as well as a rough estimate of the mass of the meteoroid.
Meteor Yet Observed
Dr. Madiedo of the
University of Huelva in Spain reported a bright meteor flash caused by a space
rock impacting the Moon’s surface at an estimated 37,900 mph (61,000 km/h),
blasting out a new crater roughly 131 feet (40 meters) wide. This impact was
observed by a pair of telescopes that are part of the MIDAS (Moon Impacts
Detection and Analysis System) observatory, at 8:07UT on September 11, 2013.
The event occurred in Mare Nubium. The meteoroid
weighed in at an estimated 880 lbs. (400 kg) and measured between 2.0 and 4.5
feet (0.6 and 1.4 meters) in diameter. More information about this event can be
IMPACT EVENT FROM FEBRUARY 2014
Bill Porter reported a
recording of a possible impact candidate from about 12:30 UTC on Feb 23.
Location was in the eastern half of Lacus Somniorum,
in the general area of Hall Y1 dome and Hall K crater. George Varros reports: “Using the Virtual
Moon Atlas, the coordinates are close to LONG 36.724 LAT 34.105 - in the
vicinity of the Hall crater.” (An image will be posted to the CosmicCorner mirror site sometime this week,
or before March 6th). The impact appeared quite faint according to
Mr. Porter, who observed this from California, USA. A comparison star was
videotaped a few minutes later ( HIP 82951A, mag
6.55). The “jury is out” on this one since it shows a gradual rise in
brightness, a peak, then a gradual fall, which is not consistent with a typical

from the Swiss-Italian Lunar Observation group. Within a day (or two or less)
of the date of this notice, images related to this report will be made
available on the mirror site. Stefano SposettiI reported the following:
Dec 7, Marco Iten, Raffello Lena, Andrea Manna
and I, made some video recordings of the crescent Moon. We got good, but also
poor sky conditions. 2 of us, Marco Iten
and I, detected independently and simultaneously a small flash on the Moon.
The image of Marco Iten shows a very nice bright
point of light, lasting about 4 fields (ie. 80 ms).
My image is a lot blurred because of wind and strong turbulence, the flash is
washed out but clearly visible at the same instant and in the same lunar
region. The airmass at the moment of the detection
was 3.9. No artificial satellites were along the line-of sight inside a 3deg
diameter centered on the Moon coordinates. We performed no photometry of the
flash. To note that Marco Iten
noticed the flash visually in real time, while looking at the laptop screen.

addition to these reports, the NASA-MSFC Meteoroid Environment Office reported,

last week of a faint impact candidate on the western (Celestial west) limb of
the moon, imaged at 11:07:24.3

Impact Observed in Europe on 1 August 2013
I received the following
report from Raffaello Lena of GLR-Italy. He writes:
“On August 1, 2013 at 02:21:55.7 UT, a small meteoroid has likely impacted the Moon' s surface. The kinetic energy transformed by the
impact into thermal energy also caused a short a flash of light that was
detected by telescopes of R. Lena, A. Manna and S. Sposetti.
The simultaneity of the flash and the same position on the lunar surface
indicates it is an impact. The event described above has been observed by Raffaello Lena (GLR group, Rome Italy) with a refractor 130
mm and with a video camera Mintron. The flash was
also detected by Andrea Manna from Cugnasco (Switzerlnd) with a Schmidt Cassegrain 200 mm and a camera watec 120N+. Stefano Sposetti (Gnosca, Switzerland) detected the flash using two
telescopes: Refractor 150 mm and SC C11” equipped with watec
Two observatories in
Switzerland are at a distance of 10.0 km. The observatory in Italy (Rome) is at
a very long distance of 558 km from Gnosca
(Switzerland). Time synchronicity of the various files is assured by using a
GPS time inserters (KIWI-OSD) and an Atomic Clock Synchronization protocol. The
meteoroidal lunar impact detected on August, 1, 2013 at 02:21:55.7 UT was
simultaneously recorded by four independent video recordings. The duration of
the flash correspond to 0.08s and reached a peak brightness of 8.3 ± 0.7 mag.
The selenographic coordinates of the lunar impact
flash are determined to 73° ± 4° E and 27° ± 3° N, near the crater Seneca C.
The examined impact flash probably corresponds to a α-Capricornids shower exhibiting favourable
impact geometry on the impact date. Enclosed an image of the
detected lunar impact. A report of the observing session (written by Sposetti, Manna and I) is published in Selenology Today 33,
which can be accessed with the following link:
Impact Yet Observed on the Moon, March 17, 2013
has observed the largest impact yet detected on the moon. At 3:50:55UT on
March 17, 2013, a flash peaking near magnitude 4.0 was observed at lunar
latitude 20.6N, longitude 23.8W. The explosion produced was the equivalent of
that produced by 5 tons of TNT. The crater generated by this explosion is
estimated to be approximately 20 feet (6 meters) in diameter and was produced
by a beach-ball sized meteoroid (about 35-cm diameter) impacting at 57,000
mph (26 km/sec), that possibly is part of a little known meteor shower called
the eta Virginids. More information about this
extraordinary event can be obtained at http://science.nasa.gov/science-news/science-at-nasa/2013/16may_lunarimpact/.
A Likely Impact
from a Sporadic Meteoroid (2011)
The GLR (Geologic-Lunar Research) group in Italy reported a very likely
lunar meteoroid impact candidate on 11 February 2011 at 20:36:58.355UT. The obsevers were Stefano Sposetti
and March Iten. Stefano Sposetti
reports, “Marco Iten and me detected a probable
impact flash on the Moon, simultaneously, from our two observatories, located
16km apart. It lasted about 4 fields (i.e. 0.08s) in one video file; a bit less
in the other video file. No artificial satellites were in a 2-deg field of view
at the moment of the detection and the two flashes in the two video files are
located at the same lunar feature.” Since impact was observed with two
telescopes separated by 16km (below the arbitrary 30km threshold that we use to
determine uniqueness) and it has been verified that no artificial satellites
were in the vicinity of the moon at the time of the impact, this can be
considered a confirmed event. More information, including analysis, can be
found at this website http://digidownload.libero.it/glrgroup/st22web.htm.
Meteors and Resources for Observers
Jovian Meteor #3
September 10, 2012, a Jovian meteor was observed by a visual observer in
Minnesota and confirmed by video in Texas. It was a two-second long, sixth
magnitude meteor that happened in Jupiter’s atmosphere. It is likely that the
object mostly burnt up in the atmosphere, as observations of the site on
subsequent rotations have yielded no markings. This event serves as a reminder
that Jupiter provides a potential wealth of information in the area of meteoritics and the interactions between colliding
planetary bodies. The story can be read at http://www.spaceweather.com/ (Select September 12 2012 under “Archives” if you do not
see a link to the story anymore). A real-time video of the impact event can be
viewed at http://www.flickr.com/photos/19299984@N08/7976507568. And check out the article published just one day before
that declares “Fireballs Light Up Jupiter” at http://science.nasa.gov/science-news/science-at-nasa/2010/09sep_jovianfireballs/.
Jovian Meteor #1,
Jovian meteor was videotaped as it happened at 18:22UT on 20 August 2010. The
event was recorded independently by two observers in Japan: Masayuki Tachikawa
of Kumamoto city was first to report the event, and Tokyo amateur astronomer
Aoki Kazuo made the confirming recording some 800 km away. More information on
this event, including pictures and video, can be seen on the August 23, 2010
page of www.spaceweather.com. Sky & Telescope also has a story on this which can be
read at http://www.skyandtelescope.com/observing/home/101264994.html.
makes the second confirmed meteor observation on Jupiter in 2-1/2 months, with
the first being on June 3rd. The June 3 and 4 (2010) page of www.spaceweather.com has more information, including an image and a video of this
extraterrestrial meteor, which occurred at 20:31 UT on June 3rd. You
can also go to the news section of Astronomy Magazine’s website (http://www.astronomy.com/asy/default.aspx?c=ss&id=26, scroll to the archives near the bottom of the page, select June
2010 and look for the link…) to get the news story. Amateur astronomers
Christopher Go (the Philippines) and Anthony Wesley (Australia) simultaneously
observed this event, making it the first ground-based confirmed observation of
an actual impact event on another world beside the moon (to my knowledge). The
impactor must have been a rather large object to have produced such a bright
flash of light as seen from a half billion miles away.
meteor did not produce any dark markings, and it is unlikely that this one will
do so as well. Both appear to be atmospheric fireballs that disintegrated
before reaching the clouds.
reinforces my suggestion (which is now being considered by others) to begin a
serious project of continuously monitoring of Jupiter for impact events. This
would need to be done at high powers, enough for 1 arc-second (or better)
resolution. A setup similar to what is used in lunar meteor or asteroid
occultation work, but with larger telescopes (at least 10-inch) and less
sensitive cameras (since Jupiter is bright) would do the trick, and could
reveal the true rate of such impacts with implications for Earth and the impact

Definitions to Describe Quality of Lunar
In order to better qualify the probability of an observation being
genuinely impact in nature, we have adopted a definitive classification
scheme. The descriptors are given below
Those impacts observed by at least two independent observers separated by
at least 50 km (30 mi) within 2 degrees of latitude and longitude on the
moon and 2 seconds of time (99% confidence).
Confirmed Observation: Those impacts observed by at least two independent
observers separated by less than 50 km (30 mi) within 5 degrees of
longitude and 5 seconds of time (95% confidence).
- Probable: Those impacts
observed by a single observer having the characteristics of an impact
observation--appearing on two or more video frames, a measurable
point-spread-function (i.e. appearing similar to a star), and/or
confidence at least 80%.
- Candidate: Any impact
observation submitted by a single observer with a confidence of at least
With these criteria in place, we
can better group observations in terms of quality and estimate the likelihood
of the observation being that of an actual impact event. It is very
possible that a candidate could be elevated to the status of
"confirmed" with the corroborative observation of a second
independent observer, as stated in the qualifications above.
