The 25cm robotic telescope FRAM-ORM at La Palma (Spain)
reacted robotically to the alert of GRB200306C (Gropp
et al GCNC 27326), obtaining a series of 20 s unfiltered
images starting at 22:51:39.3 UT, i.e. 60.3s post trigger.

We clearly detect the source reported by (Gropp et al
GCN 27326 and Lipunov et al GCN 27325), decaying at a
rate of alpha ~ 1.4 +- 0.1.  The brightness of the object
was R = 14.1 the first image.
