Abstract
The eruptive phase of the solar flare is an explosive fast process. In order to capture the evolution the flare kernel during this process, we designed a real time automatic flare onset detecting and exposure time control method for the flare observing software, with this method we can avoid the data overflow during the flare and record the fine structure of the flare’s kernel. At the same time, the software would record the GPS time of the flare onset. The software works well in the experimental test. The algorithm for flare onset detecting and exposure time control will be embedded in the routine observing software of Full-disk H-alpha telescope in Huairou Solar Observatory soon.
