MASTER robotic system (http://observ.pereplet.ru)
responded to GRB060926 (Holland et al., GCN Circ 5612).
The first image was started at 2006-09-26 16:49:57 UT, 76 s after the GRB
time. The unfiltered image is calibrated relative to USNO A2.0 (0.8 R + 0.2 B).
We see OT (Holland et al., GCN Circ 5612).
Our results:
T-T_grb exp_time m (close to R) S/N
76 s - 106 s 30 s >17 5
76 s - 360 s 5x30 s 18+-0.3
76 s - 820 s 10x30 s 18.5+-0.3
Reduction is continued.
