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.
