MASTER robotic telescope (MASTER-Net: http://observ.pereplet.ru, 200
mm, FOV=8 square degrees (testing mode)) and Very Wide Field Camera (D=50 mm,
1000 square degrees, 11 Mpx, 36" per pix, mounted on telescope) located at
Blagoveschensk was responted to the GRB 100131A (Fermi GBM alert,
Goldstein et al, GCN CIRC 10358) 76 sec after first Notice
time and 93 s after the GRB time.
The center FOV of the main telescope correspond to first alert
imformation:
RA=107.420+-3 DEC=+3.730+-3
The limit of the main telescope images is aboute 15 mag (unfiltered).
We have a number images with 5 s exposition from Very Wide Field Camera.
The image limit from Very Wide Filed Camera ~10 mag.
There is now OT in our images inside Fermi error box (A. Goldstein, GCN
CIRC 10358) brighter 10 mag.
The imege is available at
http://observ.pereplet.ru/images/GRB100131A/grb100131A.jpg .
The circles correspond to 1sigma + systematic Fermi error box, and
3sigma+systematic error box.
