Comparing the ESP/EVE/SDO flux data of 2011 Feb 6, with the counterparts of XRS/GOES and SEM/SOHO, we find that there is an enhancement that is not apparent in the two latter datasets. The enhancement, possibly regard...

This is a study designed to analyze the relationship between ground level enhancements(GLEs)and their associated solar active regions during solar cycles 22and 23.Results show that 90.3%of the GLE events that are in...
