Multi-band optical monitoring of GRB100925A/MAXI J1659-152
Abstract
We present photometric data of GRB100925A/MAXI J1659-152 obtained over several weeks after the trigger event. The multi-band observations were performed with the MITSuME 50cm telescope at Akeno Observatory and Okayama Astrophysical Observatory, the Murikabushi 1m telescope at Ishigakijima Astronomical Observatory and the 188cm telescope at Kottamia Astronomical Observatory in Egypt. The light curves of this black-hole candidate shows that the increase in brightness is about 0.4 magnitude in 2 days after the first observation. Short term variations up to 0.2 mag in one hour were continuously observed.
