MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB131224A 33 sec after notice
time and 39 sec after trigger time at 2013-12-24 16:55:24 UT in two
polarizations.
Observations were made on high (z=75 deg) zenith distance and on the
extremely stars rich field (with galactic latitude b=3 deg).
On our first (10s exposure) set we haven`t found optical transient within
INTEGRAL error-box (S.Mereghetti et. al. GCN 15607).
The 5-sigma upper limit has been about 15.5 mag
