The ROTATION REPORT is the newsletter of the ALPO Solar Section with
the primary function of promulgating the observations of the Section
members to the professional community as well as other observers. It's
secondary purpose is to bind our community of amateur solar astronomers
together with news notes and other solar information.
If you are a professional researcher and need the data listed here
contact: Richard Hill, Lunar & Planetary Lab., University of Arizona,
Tucson, AZ 85721 or email me at
rhill@lpl.arizona.edu There is no
charge for use of the data, only the request that the Section be
acknowledged as well as the individual observer. Of course contributions
to help defray mailing costs are always welcome.
All individual observers are listed below the data list. This
is done not only to give public recognition to these observers, but to
aid the professional in attributing credit.
Observations received since the last report to the end of
Sept.

News Notes
Well I didn't think it would make it to the website before rotation
1944 started but I just barely did it. This RR took nearly three weeks
to prepare. Part of that time was eaten up by my job (Ma rs observing
runs at Steward Observatory's Catalina Station) but a lot of it was due
to problems with submitt ed data. When Active Region Numbers, times,
dates, or observer names are left off of data it means a lot of
detective work for me which may or may not be successful. This all
slows the process down tremendously. In some ca ses I was only able to
get through a few images in a given night's work. Such work is why I
have often said that be ing a Coordinator means never having to say
your observing!
During the holidays I will be preparing the next summary report for the
Strollin g Astronomer (Journal of the A.L.P.O.). This will encompass
yet another year's data bringing us up to being o nly about two and a
half years behind the current date. One more such report by April or so
and we may get caug ht up to where we reasonably stay. Since we
typically get data that is anywhere from one day to six months ol d a
lag time of about a year in the summary reports seems reasonable and
will give all observers plenty of time to g et their observations in.
We still need people for the White Light Flare Patrol. This kind of
observing (s ee website for details) is best suited to those that have
only a few hours on weekends or once or twice a month, to obs erve the
sun. If you are interested in this please contact me at the email
address below.
Solar activity is a bit slack at present. Only a few naked eye groups
have been seen in the last couple months. But this stasis will
definitely not last. Be ready. Recent problems with the net at
University of Arizona have caused postings to slow a bit but we are
still getting digital data up in a day or two.
So keep those images coming and we'll get them posted.
Sunny Skies!
