This doesn't answer your question, but I got curious..

excerpted from http://www.sec.noaa.gov/ftpdir/indices/events/yesterday.txt --

2740       1903   1957      2305  HOL  3   FLA  S05E75    1F      ERU       0930

I am not an expert, but I believe this indicates that an "Optical
flare observed in H-alpha" took place between 1903 and 1957 UTC
