D. A. Perley (Caltech) reports on behalf of a larger collaboration:
The Palomar 60-inch robotic telescope responded to the Swift alert for
GRB 150203A (Ukwatta et al., GCN 17377) and began automatic follow-up at
04:11:42 UT, 155 s after the BAT trigger. The telescope acquired a
series of cycling 60-second r, i, and z exposures under good seeing
conditions.
We detect no source in or near the XRT position (Evans et al., GCN
17378), in any individual exposure or in a stack of the first several
minutes of imaging acquired in each filter. An approximate limiting
magnitude of the r-band stack (7 minutes of imaging at a median time of
13.0 minutes post-trigger) is >21.5 mag, calibrated relative to USNO B1.0.
Given the low galactic latitude, no further follow-up is planned.
