One of the four  MASTER Very Wide Field Cameras located at Kislovodsk
(http://observ.pereplet.ru/, D=50 mm, 4x1000 square degrees, 35'' per pix)
has observed  Fermi  error box  (Trig Num 251059717) with 5s exposures during 
all night without time gap between images (Gorbovskoy et al., GCN Circ 
8671, 8672).

The SGR 0044+42 error box (Mazets et al., arXiv:0712.1502v1 
astro-ph, http://arxiv.org/abs/0712.1502v1) is inside Fermi error box.
This is in agreement with our suggestion that Fermi Trig Num 251059717 is 
SGR (Lipunov & Gorbovskoy, GCN Circ 8673).

Our unfiltered images are calibrated relative to Tycho stars (V).
The magnitude limit of the each emage is  ~11m.


The film of our observations are available at

The reduction is continued.
