We perform a statistical study of the decay times for the recovery phase of the 300 most intense geomagnetic storms that occurred between Jan. 1, 1957 and  Dec. 31, 1998. Using the data set in this study and the facility web access to GOES satellite data, we selected a set of storms from 1986 and 1998 and investigated their solar origin.
