S. Mereghetti, D. Gotz, J. Burkowsky,
the INTEGRAL Science Data Center and the INTEGRAL Science Working team
report the detection of GRB021219 at 07:33:57 UTC
in the field of view of the IBIS telescope on board ESA's INTEGRAL
satellite.
The burst lasted about 4 seconds and had a peak flux of about 1-2
10^-7 erg/cm2/s in the 25-100 keV range.
The preliminary position is RA 18h50m and DEC +31deg 52s with an
uncertainty of 20' (radius) dominated by systematics.
A refined position will be reported as soon as available.
This message is citable.
[GCN OPS NOTE (19dec02): Due to a typing mistake the GRB declination
in GCN 1766 was reported as +31deg 52s. The correct value is +31deg 52min

D.Gotz (IASF-Milano), P.Favre (ISDC), S.Mereghetti (IASF-Milano),
J.Borkowski (ISDC), and the INTEGRAL Science Working team,
report:
This burst (GCN 1766, 1767, 1768) was also observed by Ulysses.
Although the INTEGRAL timing is still undergoing refinement, we have
triangulated it assuming a systematic uncertainty of 100 ms, which is
supported by recent SGR observations. The preliminary annulus is
centered at RA, Decl(2000)= 182.935, 36.337 degrees, with radius
78.549 +/- 0.023 degrees (3 sigma ). This annulus intersects the
INTEGRAL error circle given in GCN 1768 at two points:
RA DEC
282.557459=18 H 50 M 13.79 S 31.832096= 31 o 49' 55"
282.642596=18 H 50 M 34.22 S 31.932013= 31 o 55' 55"
This reduces the error box size to about 15 square arcminutes.
This annulus may be improved. A map has been posted at

K. Hurley and T. Cline, on behalf of the Ulysses GRB team, and
D.Gotz (IASF-Milano), P.Favre (ISDC), S. Mereghetti (IASF-Milano),
J. Borkowski (ISDC), and the INTEGRAL Science Working team,
report:
The IPN annulus actually intersects the INTEGRAL error circle given in
GCN 1768 at four points, not two:
RA DEC
282.572616=18 h 50 m 17 s 31.849899= 31 o 50 ' 59 "
282.664692=18 h 50 m 39 s 31.957916= 31 o 57 ' 28 "
282.546093=18 h 50 m 11 s 31.898856= 31 o 53 ' 55 "
282.601577=18 h 50 m 24 s 31.963983= 31 o 57 ' 50 "
Thus the agreement between the annulus and the error circle is
improved, but the error box size increases to about 22 square
arcminutes. A revised map has been posted at
ssl.berkeley.edu/ipn3/021219.

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.

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."

"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".
