The AAVSO SID Events data are now back on-line at NOAA/NGDC after a few years hiatus;
Ionospheric data services pages:

1 - Extending the SID tables
http://www.ngdc.noaa.gov/stp/space-weather/ionospheric-data/sids/tables/>
back in time by extracting the relevant pages from the SGD reports
http://www.ngdc.noaa.gov/stp/solar/sgd.html as far back as possible. Include improved readme file,

2 – NGDC is now providing secondary access to the AAVSO listings
http://www.ngdc.noaa.gov/stp/space-weather/ionospheric-data/sids/aavso/ of SIDs with readme file:
