The Solar Bulletin of the American Association of Variable Star Observers (ISSN 0271-8480) is the publication of record for observational data relating to sunspot and sudden ionospheric disturbance (SID) observations by Solar Section observers of the AAVSO. The Solar Bulletin is published monthly in the calendar month following the cover date (i.e. the January issue is published in mid-February, and contains data for January). It has been published regularly with few interruptions since 1944.
The AAVSO Solar Bulletin is currently listed in the NASA ADS Abstract Service under journal code "AAVSB". If you use AAVSO solar data or the bulletin in your publication, please cite the data accordingly; more importantly, please let us know that you use these data! We would appreciate receiving a copy of any and all publications that reference AAVSO data; please send offprints or links to abstract pages to firstname.lastname@example.org.
Active solar observers receive a copy of the Solar Bulletin each month. Institutions and other entities may subscribe to the Solar Bulletin for a fee. See our subscriptions page for details.
Note that data from the AAVSO Solar Section are only available either via the Bulletin or via NOAA's National Geophysical Data Center. We are working toward making these data available electronically via the AAVSO website in the very near future.

Volunteers wanted! If you're local to AAVSO Headquarters (Cambridge, Massachusetts) and are interested in helping us scan paper copies of the Solar Bulletin from 1964 backwards, please contact email@example.com. Alternately, if you have your own copies of the bulletin and can provide scanned PDF, JPEG, or PNG files, please let us know.
Many thanks to our first volunteer, Roberto Battaiola of Italy, for providing us with scans of Volumes 45 to 57! Thanks also to David Schmitt of the UC San Diego Engineering Library for help acquiring missing issues!
We will work to place earlier issues of the Solar Bulletin online as time and resources permit. Watch this page for progress in 2011 and 2012.
