GCN Circular 7695
D. A. Perley, J. S. Bloom, and W. Li (UC Berkeley), on behalf of a larger collaboration, report: We have continued to monitor the optical transient (Perley et al., GCN 7678) associated with GRB 080503 (Mao et al., GCN 7665) using Gemini-N (+GMOS) with additional exposures in r-band nightly since the event. The optical counterpart remains detected in all images to date (through 2008-05-07 UT) and is significantly, but slowly, fading. This confirms the lack of further rebrightening (see also Perley et al., GCN 7680) and further distinguishes the behavior of the transient from ordinary long- and short-burst afterglows. Alternatively, a faint host galaxy could be contributing to the later exposures somewhat; further follow-up may help resolve this ambiguity.
