and Jens Hjorth (DARK, NBI) report:

Using MOSCA on the 2.56-meter Nordic Optical Telescope, we
obtained 3*300 s R-band images of the GRB 060502A field
(La Parola et al., GCN#5047) on May 3.21 (1.08 days post
burst). At the location of the optical afterglow (Pool et al.,
GCN#5068), 0.7 arcsec outside the XRT borders (La Parola et al.,
GCN#5054), we detect a source with R = 22.5. Combined with
the R-band magnitude reported by Hicken & Garnavich (GCN#5070),
this implies a decay slope of alpha = 1.0.

An image of the field is shown at:
