H. Pedersen, B. L. Jensen (CUO), A. Järvinen (NOT) and 
M. I. Andersen (AIP) report:

On 2003 August 2.92 UTC, we observed the position of the VLA 
afterglow candidate (GCN #2280, #2341; Coburn & Boggs 2003, 
Nature, 423, 415) with the 2.5-m Nordic Optical Telescope, 
La Palma. We obtained 10 R-band exposures, each of 10 min 
duration, in a seeing of 0.9" FWHM.

According to a standard calibration, we estimate that any 
unresolved object at the VLA position is fainter than 
m(R) = 25.4 (2 sigma).

A box-car smoothed 45" x 45" section is displayed on:
