We  (MASTER-Net: http://observ.pereplet.ru, Tunka, Ivanov et al., 
GCN Circ 11161) clearly detected optical flare   (maxmag~17.0,unfiltered) at 426+-40 s   after 
trigger time (Immler et al., GCN Circ 11159)  synchronously  with 
Xray flare  (Page et al.,  GCN Circ 11171).

We have ~ 11 hours Unfiltered, R,I, Polarization continuously 
observations on same telescope systems. The redaction is continued.

The first 10 000 s relative optical flux light curve  is 
available at http://observ.pereplet.ru/images/GRB100901A/opt_flux_lc.png
