GCN#1119) starting at 13:40 UT on 30 Oct 2001 with the 1.0-m telescope at Nainital (India) and at 18:05 UT at the 1.23-m telescope at the German-Spanish Calar Alto Observatory (CAHA). A preliminary analysis of the images reveal no optical counterpart within a 5' radius down to R = 21 when comparing with the DSS-2 R-band chart. Further R- and I-band observations are in progress."
