on behalf of larger Indian GRB collaboration).
GRB 120311B field (Marshall et al., GCN Circ 13038) was observed
with the newly installed 1.3m Devasthal Fast Optical Telescope at
Nainital. Several images in R_c pass-band (300 sec each) were taken
in two sessions starting at UT 21:11:10, 11-03-2012.
In the initial co-added R_c frame (3x300sec), we did not detect any
new optical source within the XRT error-box (Osborne et al.,
GCN Circ. 13042) down to a limiting magnitude of ~ 20.5 mag.
The photometry was done in comparison to nearby USNO- B1 stars.
