TITLE: GCN CIRCULAR NUMBER: 12941 SUBJECT: GRB 120212A: NOT optical observation DATE: 12/02/12 21:37:27 GMT FROM: Dong Xu at Weizmann Inst D. Xu (WIS), D. Malesani (DARK), G. Barisevicius (NOT), B. Nordstrom, J. Andersen (NBI), P. Jakobsson (U. Iceland) report on behalf of a larger collaboration: We observed the field of GRB 120212A (Sonbas et al., GCN 12930) using the 2.5m Nordic Optical Telescope (NOT) equipped with the ALFSOC camera. We obtained 4x200s R-band images with a median time 19:52:24 UT on 2012-02-12, i.e., 10.7 hrs after the BAT trigger. The optical afterglow of this burst (Guidorzi et al., GCN 12932; Hoversten et al., GCN 12933; Kawabata et al., GCN 12935; Kuin et al., GCN 12940) was clearly detected in our stacked image and had R ~ 20.1 mag calibrated with nearby stars in the USNO B1 catalog.
