Very energetic flares and CME may strongly influence Space Weather and Earth environment. In the last years, there has been growing interest in the possibility of forecasting flare occurrence, in order to reduce damages to spacecraft, satellite positioning systems and effects on RF communications. In this context, we have carried out a statistical analysis on a number of parameters characterizing sunspot-groups, hosting very energetic flares. We have used data on sunspot-groups, a part collected at INAF-Catania Astrophysical Observatory during 1998 - 2002 and a part deduced by NOAA reports, together with data on M and X flares obtained by GOES 8 in the soft X-ray range. The results obtained by this analysis may contribute to a better knowledge of the flare phenomenon and could improve the capabilities of Flare Warning Services....

Abstract
Very energetic flares and CME may strongly influence Space Weather and Earth environment. In the last years, there has been growing interest in the possibility of forecasting flare occurrence, in order to reduce damages to spacecraft, satellite positioning systems and effects on RF communications. In this context, we have carried out a statistical analysis on a number of parameters characterizing sunspot-groups, hosting very energetic flares. We have used data on sunspot-groups, a part collected at INAF-Catania Astrophysical Observatory during 1998 - 2002 and a part deduced by NOAA reports, together with data on M and X flares obtained by GOES 8 in the soft X-ray range. The results obtained by this analysis may contribute to a better knowledge of the flare phenomenon and could improve the capabilities of Flare Warning Services....I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
