MAXI/GSC triggered at 2012-01-27 04:21:52 UT on an uncatalogued X-ray transient source. The transient emission lasted for about 10 seconds within the 50 second long triangular transit response of MAXI/GSC. We identify this event as GRB 120127A. Assuming that the source flux was constant over the transit, we obtain a statistical 90% C.L. elliptical error region centered on (R.A., Dec) = (139.14...Full Text

The Swift/UVOT began settled observations of the field of GRB 120121A 124 s after the BAT trigger (Page et al., GCN 12885). No optical afterglow consistent with the XRT position (Evans et al., GCN 12888) is detected in the initial UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC)...Full Text

We have analysed 9.8 ks of XRT data for GRB 120121A (Page et al. GCN 12885), from 130 s to 23.1 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN. Circ 12888). The light curve can be modelled with a power-law decay with a decay index of alpha=0.88 (+0.09, -0.08). A spectrum formed from the PC...Full Text
