MASTER-Net robotic telescopes (MASTER-Net: http://observ.pereplet.ru)
located near Ekaterinburg (Kourovka) and Tunka (Baykal Lake) was pointed
to the Swift GRB 101008A (Baumgartner et al., GCN#11318, GCN#11319;
Beardmore et al., GCN#11321) 53 s after trigger time (immediately after
roof opening and with last night focus) and 8309s after trigger time (the
Tunka delay was due to weather conditions).
Time duration of the GRB 101008A is 104 +- 35 sec (Barthelmy et al.,
GCN#11327). So we have prompt optical limit at Kourovka site.
We see marginaly possible OT (S2, Moskvitin et al.,GCN#11324; Nardini et
al., GCN#11326) at Tunka observations.
We have next unfiltered estimation:
t_start-t_trig(s) mean time exp_time(s) m Coadd?
