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.
