We clearly see (MASTER-Net: http://observ.pereplet.ru, Tunka) 
OT after 386 s (T-T_trigger) at the 
Swift position (Immler et al., GCN Circ 11159) and strongly brighter than 
UVOT estimation (Immler et al., GCN Circ 11159).
After this time we see power low decay F ~ t_(-alpha), with alpha ~ 
0.5+-0.2.

This is preliminary result.  Observations are continued at Tunka, Ural 
and Kislovodsk in different filters.
