report:
The 2-m LCOGT Faulkes Telescope North in Hawaii began observing Swift
GRB 150910A (Pagani et al. GCN 18264) on September 10, 09:33:19 UT (28
minutes after the burst trigger) with SDSS r and i filters. We clearly
detect the optical afterglow (Pagani et al. GCN 18264; Zheng et al. GCN
18265) with the following magnitudes:
Mid Time Exposure Filter Magnitude
(min) (s)
-------------------------------------------------------
29.0 60 r' 16.60 +- 0.02
35.6 60 i' 16.42 +- 0.02
-------------------------------------------------------
Calibration is done against SDSS magnitudes of nearby stars.
