GRB 201203A: FRAM-Auger optical limit

report: The 30 cm robotic telescope FRAM-Auger in Malargue (Argentina) reacted robotically to the Swift/BAT alert of GRB201203A (Dichiara et al., GCNC 28985), starting with a series of 20 s unfiltered images at 06:54:04 UT, i.e. 97 s post trigger. We do not detect any new or strongly variable source at or around the reported gamma-ray errorbox in single frames or a combined 20 x 20 s image taken between 1.5 min and 12.5 min after the initial trigger. The combined exposure has a limiting magnitude r'(AB) ~ 17, as calibrated against the Atlas Catalogue.
