The New ALPOSS Online Archive

As some of you may have noticed, the ALPO Solar Section has a new online archive, where submitted solar observations and images are being kept. They can be accessed by anyone who has an interest in reviewing them. This official ALPO Solar Section Online Archive is not to be confused with the “ALPO Archive” which is graciously maintained separately by the Arkansas Sky Observatory, but is instead the official ALPO archive where members are encouraged to post their images and observations. This ALPO Solar Section Online Archive is also different than the online archives of some other organizations, which are accessible by File Transfer Protocol (ftp) and where images need to be downloaded to be reviewed.

At the current time, the ALPO Solar Section Online Archive houses almost 28,000 images and observations that were submitted by observers and kept in an off-line archive. It is our feeling that in today’s world of social media and fast internet access, we needed to adapt to the new technologies. We have done so with the creation of the ALPO Solar Section Online Archive and letting everyone see what many dedicated observers over the entire world have done to document the activity of the Sun since 1979, which is the earliest image we have in our archive. Please take a look at what’s there at: .

If you would like your images to be part of the ALPO Solar Section Online Archive and contribute your own observations, please attach your images (which must contain the information requested in the Summary) to an email and send them to
Or if you are a member of ALPO, you can upload your images directly to the ALPO Solar Section Online Archive, but have to register first by sending an email with your name and intentions to upload observations to the above email address. You will be sent a guide and information on how you can upload the images yourself. We hope that you will enjoy this change as much as we do.
Happy New Year and lots of  Clear Skies,

The Carrington event of September2, 1859!

From Spaceweather- September 2nd, 2015

Today is the anniversary of an historic solar storm, the Carrington Event. On Sept. 2, 1859, a CME struck Earth’s magnetic field with such power that telegraph stations caught fire and people in Cuba read their morning newspapers by the red light of the aurora borealis. If a similar storm struck our planet today, it might cause trillions of dollars of damage to society’s high-tech infrastructure. Could the Carrington Event happen again? It almost did just a few years ago. Extreme solar storms–past, present and future–are highlighted on today’s edition of

I’m not at all disappointed!

Happy New Year Everyone!

As the clouds are slowly departing from Ontario Canada, we might actually see the sun. I can see from NOAA and Spaceweather there is still a sunspot AR11039 appearing in the lower southern hemisphere.

As this Solar Cycle 24 starts to come alive, lets hope for clear observing conditions.

I also urge you all to send in your solar observations to the Solar ALPO Coordinator at so these can be archived for use by researchers and amateur solar observers.

Please include the time in UT Time, orientation of North at the top (for images) type of equipment used, location. Please see the page on ALPO Report forms . Remember to join the ALPO Solar Email group on Yahoo.

Welcome to the Solar Blog

Each ALPO section now has access to a “blog” and an image gallery.  The blog can be used by any coordinator or section associate to post special alerts and images.  The gallery is also available for posting and archiving section images.

There are many advantages to using these applications on our website, including the ability to search posts by category, content and the ability to perform keyword searches when looking for images.  There is also an option that will automatically post to a Yahoo group whenever a post is logged to your blog.  The blog also includes an events calendar.   The best part is that you don’t have to wait for someone else to post your alerts.  Posting an alert to the blog is just like creating a Word document.  You simply type, cut and paste images and post – no web experience necessary.

Of course this is all optional.  If you like the way things are now with your section, that’s fine.  Please note that the gallery will be used for future image posts, if the webmaster is asked to post images for you.

If you need an account for your section, contact Larry Owens

Here’s a link to the gallery:
