report:
"On Dec 4.16 UT we observed the field of the short
/hard GRB 021201 (GCN 1719) with the 2.5-m Nordic
Optical Telescope (+ALFOSC) at the Observatorio del
Roque de los Muchachos, in order to monitor the
entire IPN error box. In the co-added image (5 x
900-s in the r' Sloan filter with a 2".8 seeing),
no optical transient is found when comparing to the
DSS-2 (R-band). Particularly, a point-like optical
source with R about 20.5 is found at coordinates
RA(2000) = 08 07 49.35, Dec(2000) = +21 12 33.8
(+/- 0".5); this is within 2" of the Chandra
source # 10 reported to be inside the IPN error box
(GCN 1741). Such object is visible in the blue and
red DSS-2 charts as a very blue source that does
not seem to be related to the GRB 021201. Further
observations are planned."
