report:

"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)."
