GCN Circular 3984
J. S. Bloom and K. Alatalo (UC Berkeley), on behalf of a larger collaboration, reports: "Starting at 2005-09-15 11:33:18 UTC, the 1.3m PAIRITEL on Mt. Hopkins began imaging the field of GRB 050915 (Swift trigger 155242; GCN 3977). In a stack of exposures amounting to 1130 sec of integration time we detect a red source at (J2000): RA 05:26:44.83 DEC -28:00:59.5 The position is uncertain to about 400 ms but may be improved with further analysis. This source appears to be consistent with the revised XRT position (Grupe et al. GCN 3983). Since the source is significantly more faint than the 2MASS detection level, we make no claims about variability at this time. Further analysis is in progress."
