The 25cm robotic telescope FRAM-ORM at La Palma (Spain) reacted robotically
to the INTEGRAL alert of GRB201214A (Mereghetti et al., GCNC 29037),
obtaining a series of 20s unfiltered images starting at 06:19:23.3 UT, i.e.
32.8s post trigger.

We do not detect any new or strongly variable source within a 20 arcmin FOV
around the reported gamma-ray errorbox - neither in single images
(detection limit R>~18.0) nor in a combined 40x20s frame (mean exp time
541s post trigger, with a limit R>~19.5).
