report:
"We have imaged a 7' x 7' region centred on the
error box for GRB 020304 (Hurley et al., GCN 1854)
with the 1.5-m telescope at Observatorio de Sierra
Nevada in Granada, Spain. One unfiltred frame and
one R-band frame (300-s exposure time each) were
obtained on Feb 4.879 UT (i.e. 8.3 hours after
the GRB) under poor meteorological conditions.
When comparing to the DSS-2 (R-band), no optical
counterpart is found down to a limiting magnitude
of R = 19.7 in the central region (coverage ~35%)
of the error box."
