report:


The 30 arcmin error box of the X-ray transient 011130 (GCN/HETE BURST
POSITION NOTICE; 1864, Seq_Num: 3) was surveyed with the Calar Alto
1.23-m telescope in R and I on November 30, starting 22:45 UT, i.e.,
about 16.5 hrs after the burst trigger. Seeing was ~ 1.2 arcsec. The
images completely cover the revised error box (Ricker et al., GCN
#1169Not found
 
 
). Because of the bright, full moon close to the error box, the
limiting magnitude of the images is only about R, I = 18.5 to 19. A
careful comparison with the DSS2 red survey did not reveal any potential
OT candidate (see also Fox et al., GCN #1170Not found
 
 
). Naturally, some faint objects 
visible on our I-band images have no counterpart on the corresponding 
R-band images. Their nature remains to be checked.

This message is quotable.
