Z. Cano (Liverpool JMU), C. Guidorzi (U.Ferrara) report on behalf of a
larger collaboration:
We observed the optical afterglow of GRB 100814A (Schaefer et al., GCN
11086; Beardmore et al., GCN 11087) with the 2m Liverpool Telescope,
starting at 22:16:09 UT on the 16th of August 2010, in filters r and i.
We clearly detect the afterglow in both filters with the following
magnitudes:
======================================
Filter T-To (days) Mag
--------------------------------------
R 2.96 19.75 +/- 0.02
I 2.93 18.32 +/- 0.04
======================================
The photometric calibration is performed against USNO-B1 objects
0720-0016107 (R2=19.58) and 0719-0016667 (I=17.27). Our detection is
consistent with the values reported by Malesani et al. (GCN 11121).
Observations are ongoing.
