We observed the field of GRB 101219A (Gelbord et al., GCN 11461) with
StanCAM mounted
on the NOT telescope on La Palma, Canary Islands (Spain) starting at
3:34 UT (~1 hour after
the trigger) and ending 4:01:21 UT.
We took seven images in R band with an exposure time of 150 seconds
each. The stacked
image does not reveal any new source within the XRT error circle
(Gelbord et al., GCN 11461),
and in particular at the location of the optical object identified by
Perley et al. (GCN 11464).
We derive a limiting magnitude of 21 in R-band calibrated against USNO
stars with a
mid-exposure time of 1.27 hours after the trigger.
