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
