SolarMonitor's flare prediction system's probabilities are calculated using the NOAA Space Weather Predicion Centre's McIntosh classifications. There are two methods, MCSTAT and MCEVOL, that use sunspot-group McIntosh classifications and Poisson statistics to calculate flaring probabilities valid for a 24-hr period starting at 00:00 UTC. The flaring probabilities are calculated using historical data from solar cycles 23 and 24 (1996-2019).

MCSTAT (McIntosh Statistics): Uses the point-in-time McIntosh classification to calculate Poisson flaring probabilities. Details about the method [1] and forecast verification testing [2] can be found in the following papers:

MCEVOL (McIntosh Evolution): Uses a combination of previous and current McIntosh classification to calculate Poisson flaring probabilities. Details about the method and flaring rate statistics can be found in the following:
