"We have obtained a series of R and I-band observations, using
the ALFOSC instrument at the Nordic Optical Telescope
Date 2000 UT Exp. Seeing FWHM Magnitude
Sept 15.097 4 x 420 s R 1.5" >20.50
Sept 15.097 4 x 420 s I 1.2" 21.05 +/- 0.30
The radio/optical candidate (ref. Berger et al., GCN 795;
Price et al., GCN 796; see also GCN 798 and 799) is well
detected in the I-band sum image.
The photometry was done relative to standard stars measured
at USNO (cf. GCN 800)."
