TITLE: GCN CIRCULAR NUMBER: 13111 SUBJECT: GRB 120326A: Liverpool Telescope observations DATE: 12/03/26 06:50:26 GMT FROM: Cristiano Guidorzi at Ferrara U,Italy C. Guidorzi (U. Ferrara) reports on behalf of the LJMU GRB group: The 2-m Liverpool Telescope automatically observed Swift GRB 120326A (Siegel et al. GCN Circ. 13105) on March 26, from 01:34:07 UT, corresponding to 13.6 minutes after the BAT trigger time. Within the XRT error circle we clearly detect the optical afterglow (Klotz et al. GCN Circ. 13107, 13108; LaCluyze et al. GCN Circ 13109) with the SDSS riz filters at the following position 18:15:37.13 +69:15:35.7 (J2000) uncertainty of 0.3". We estimate the magnitude of the afterglow as follows: Mid time from Exp Filter Magnitude GRB (min) (s) --------------------------------------------- 14.1 3x10 r 19.1 +- 0.2 44.8 120 r 19.6 +- 0.1 --------------------------------------------- Magnitudes are calibrated against nearby USNOB-1 stars.
