Observatory) report:
"A preliminary analysis of one 20 min. R image of the field of GRB 000630
(GCN 736) obtained on june 30.89 UT with a seeing of 1".8 reveals a possible
candidate at RA = 14 47 25.3, DE = +41 12 28 (error 2") not present in the
DSS2. A comparison with respect to the USNO 1275-08523886, 1275-08523650 and
1275-08523956 stars gives R= 20.5+-0.2 and a limiting magnitude R = 21.
Further observations are needed to confirm the proposed identification."
