MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
instaleted several days ago in South African Astronomical
Observatory (Sutherland) automaticaly was pointed
to the Fermi_LAT GRB141222A (McEnery et al., GCN 17218) after error box
rised at 2014-12-22 22:34:35 UT (15.5 hours after trigger time) in
unfiltered regime.
Because we have no reference images we can only use DSS stars.
There is no any optical transients brighter 20.8 unfiltered magnitude
inside error box (between 2014-12-22 22:34:35 and 2014-12-23 00:26:09).
We note that error box has small Galactic Latitude b = 4.3 but no very
big absorption in R and I, they are 0.9 and 0.7 correspondently (Schlafly
& Finkbeiner 2011, ApJ 737, 103).
