MAXI GSC detected a gamma-ray burst (GRB 100823A). The image and the light curves of the burst are shown below. The position of the source came into the field of view of MAXI GSC ~10s before the trigger of Swift/BAT. The burst was seen for about 25s within the transit of ~50s.

MAXI/GSC detected GRB 100510A on 2010-05-10 from 19:27:09 to 19:27:37 (UT). It is temporary coincident with the Fermi-GBM Trigger #295212428. The source is clearly seen in the all-sky image (top figure). The error region is shown in the middle figure. Here, the 90% statistical error region is shown in small box, assuming the constant flux during the 50 sec scan transit of MAXI FoV. The larger box shows the error region without assumptions on the source constancy. The upper-right region (a part of large circle) shows the error region of Fermi-GBM flight position (The ground position is inconsistent with the MAXI position). The bottom figure shows the light curve of the burst. The details are reported in the GCN circular.
