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.
The database is organized as ASCII files, each containing only the SID events recorded in the listed month. The file format begins with a list of observer IDs to recognize the observers who contributed to that monthly report. The list of SID events follow with the date, event peak time (UT), and the importance rating for each event on consecutive lines. The events are ordered chronologically. The bottom lines of each file provide a distribution of the SID events in terms of importance rating. A monthly total is also listed.
The SID Database is a work in progress. Hardcopy lists published in the AAVSO Solar Bulletin are manually entered and formatted to create each file. As each month is converted and verified, the files will periodically be added to the database webpage. The work is time-consuming, but worthwhile since the final product will allow efficient electronic searches and more detailed statistical analyses of the SID program results going back to 1958. Many SID observers have contributed to this data set over the years. The final database serves to recognize their efforts and honor their diligence in providing this scientifically valuable data on a voluntary basis.
