Observations on MASTER robotic telescope at Tunka (MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, pp. 1-7) are continued (Ivanov et al., GCN CIRCULAR 11228,
Gorbovskoy et al., GCN CIRCULAR 11231).
We have very smoth light curve up to 4 hours after trigger time.
The power low index afterglow decay (F~T_alpha) apha is equal -0.83+-0.02
.
The preliminary 20 min automatical light curve is available at

(unfiltered).
This automatical pohtometry calibrated by USNOB1 stars.
