Bright points in UV continuum in a M9.1 flare
Abstract
Using the data of RHESSI SOHO MDI SOHO EIT and TRACE white light and 1700 AA images we analyze a gradual two-ribbon M9 1 solar flare occurred on 2004 July 22 We find some bright points appeared in white light and 1700 AA images alone the flare ribbons with the lifetime of several minutes Some of them have rapid movement in weak magnetic field regions with sharp contrast and small area We identify these short-lived brightenings as mainly at the least UV continuum enhancement Our primary result shows that the brightenings do not appear in the HXR main sources These new phenomena may provide a new challenge for the classical flare scenario
