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".

E. Berger (Caltech) and D. A. Frail (NRAO) report on behalf of a larger
collaboration:
"On December 20.03 UT we used the VLA at 4.86 GHz to observe the error box
of GRB 021219 (GCN 1766). We detect a single radio source within the
refined IPN+INTEGRAL error region (GCN 1772), which is visible in the NRAO
VLA Sky Survey (NVSS; Condon et al. 1998, AJ, 115, 1693). There are no
additional sources down to a 4-sigma limit of 220 microJy."

A. Henden (USRA/USNO), J. Hambsch (VVS/AAVSO), E. Broens (VVS/AAVSO) report:
We have imaged the entire error circle of GRB021219
(Mereghetti et al., GCN 1766; Gotz et al., GCN 1768)
with the following results:
UTD dt(burst) tele exp filt condx lim_mag
021219.78 11hr 0.4m 8x5min Rc poor 18.0
021220.06 18hr 1.0m 12min Ic poor 19.5
Comparison with the DSS-2 F and N plates show only a few objects
near the plate limit that may or may not be real, but no new
bright object. No galaxies are seen; at galactic longitude 61.8
and latitude +14, this field is relatively close to the galactic plane.
No additional observations are planned.
