Flares Research at the Maximum of Solar Cycle 22

Project Description
This project involved the multiwavelength/multispacecraft
observations of solar flares on October 22, 2001. After a lull
in major solar activity that began in September, the Sun
reasserted itself with 3 major flares in four days. The
most-energetic class, the X-class, occured on the 19 and 22
October, in two regions separated by 90 degrees of longitude.
