This was the closest thing I found. Sorry if its useless.


ALGORITHM AND PREDICTABILITY

The algorithm was tested through a retrospective prediction for the period from 11 to 25 December 1990 (the polarization distribution and the ratio Nb/Nf were taken into account). During this period, 7 AR’s crossed the solar disk, in which 20 flares of importance ³ M1.0 and 2 flares of importance ³ X1.0 were recorded. The forecast in terms of flares scored 60%, and no false alarms occurred. Thirty-eight cases of no flares were predicted for all AR’s during the above-indicated period, with 79% predictability; flares were recorded in 8 cases (21%) with "no" prediction.


Here's the article I got it on: SHORT TERM PREDICTION OF POWER SOLAR FLARES FROM SSRT DATA

Not sure if this will help or not but here is a link to the
NOAA's solar activity sight might take a little reading to learn how to interperet the figures but they have been keeping records of solar activity
since the turn of the century
