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).
