report:

"On Dec 20.74 UT we observed the field of the GRB 021219
detected by INTEGRAL (Mereghetti et al. GCN 1766) with
the 1.5-m Telescope at the Observatorio de Sierra Nevada in
Granada, in order to monitor the entire IBIS-IPN error box
(Hurley et al. GCN 1771, Gotz et al. GCN 1772). In the co-
added image  (6 x  300-s in the Johnson R-band filter with
a 2".5 seeing),  no optical transient is found when comparing
to the DSS-2  (R-band) down to R = 20.5".
