E.Pavlenko and V.Rumyantsev (on behalf of Crimean Observatory and Space
Research Institute (Moscow) GRB follow-up teams) report:
"We have imaged of the error box for GRB 020317 / HETE #1959
with the 0.38-m Cassegrain telescope of Crimean Astrophysical Observatory
(field 7x10 arcminutes).
5 x 300 sec R-band images partially covering the error box of the possible optical
afterglow of GRB 020317 were obtained between March 17 UT 20:14:19 and
20:45:31, i.e., in 2 - 2.5 hrs after burst. The limiting magnitude was 18.5 (R). We
found a faint object (R=18.2+/-0.3 mag, UT 20:37:35) located at the 0.9 arc min to
the East from the star R=16.9 RA(J2000) = 10 24 27.99 Dec(J2000)= +12 36 05.6
(USNO-A2.0) which is not in DSS. The bad weather conditions did not allow to complete
the covering of error box and obtain more observation of this faint object."
This message is quotable.
