report:
The 25cm robotic telescope FRAM-ORM at La Palma (Spain)
reacted robotically to the alert of GRB201015A (D'Elia
et al GCNC 28632), obtaining a series of 20 s unfiltered
images starting at 22:50:50.8 UT, i.e. 37.6s post trigger.
We clearly detect the source reported by other telescopes
(Lipunov et al. GCN 28633, Malesani et al GCN 28637, Ackley
et al GCN 28639 and others). As reported before, the
brightness of the object reaches a maximum about 5 minutes
after the trigger with R ~ 16.5 and then decays until the
end of our dataset 2.4 h after the trigger.
