report:
The 25cm robotic telescope FRAM-ORM at La Palma (Spain)
reacted robotically to the Swift alert of GRB201029A
(trigger=1003002; Dichiara et al., GCNC 28803), obtaining a
series of 20s unfiltered images starting at 20:21:23.0UT, i.e.
93s post trigger.
We do not detect any new source in the XRT error box neither
in single images (3-sigma limit R>~15.7) nor in a combined
20x20s frame (mean exp time 276s post trigger, 3-sigma limit
R>~18.15) similarly to Lipunov et al. (GCNC 28804).
