SunEntry is a data entry program for solar observers. It will help you to create reports and send them to our database where they will be used in the AAVSO American Relative Sunspot Program. The information you submit will also be used in the monthly Solar Bulletin.
Before you can use SunEntry, you must have an AAVSO website account and an AAVSO Observer code if you don't already have both. Here are instructions on how to get them:

About the SID database
The Sudden Ionospheric Disturbance (SID) Database lists all events identified in the AAVSO Solar Bulletin. These results are provided monthly by the worldwide network of SID observers in the AAVSO Solar Division. Individual results are correlated with other observers' reports and reduced to a list of events with high definiteness ratings.
