MASTER Fermi GRB110120A observations

MASTER II robotic telescope at Kislovodsk

MASTER VWF cameras composed 1 sec exposition images (60 coaded images from two cameras) started from 64 sec after trigger time. Rectangles are the bad pixels. Rectangle is the results of the IPN triangulation (Hurley et al., GCN 11595) Two circles are the Fermi LAT errobox (3 sigma and 1 sigma correspondingly)
