From
Shashi Bhushan Pandey at ROTSE <shaship@umich.edu>
Brajesh Kumar, Vijay Kumar Bhatt and S. B. Pandey (ARIES, Nainital, India,
on behalf of larger Indian GRB collaboration).
We observed the Swift GRB120219A (trigger=515375, Swenson et al. GCN 12964)
with the 104cm telescope at ARIES Nainital starting ~ 22 minutes after the
burst i.e. at 14:52:46 UT and onwards. Several images were taken in R_c
and I_c pass-bands.
In the co-added R_c frame (200sec + 2*300sec), we did not detect the
optical transient reported by Xin et al. (GCN 12966) down to a
limiting magnitude of ~ 20.5 mag. The photometry was performed
in comparison to nearby USNO- B1 stars.
