Starting at the beginning of 2005, the Moscow-Vostryakovo MASTER station carried out observations of 31 GRBs (Table 2). In 16 cases, we obtained the first upper limits on the optical fluxes of the GRBs, i.e., fluxes brighter than which no optical candidate for the GRB was detected.

GRB Optical flare discovery Lipunov et al., 2007ARep.,Vol. 51, p.1004 MASTER robotic system ( responded to GRB (Holland et al., GCN Circ 5612) under the good conditions (V. Lipunov et al., GCN Circ 5632). The first image was started at :49:57 UT, 76 s after the GRB time (355 mm telescope, 6 square degrees FOV, 2.1'' per pix, CCD Alta U16). The unfiltered image is calibrated relative to USNO A2.0 (0.8 R B). We find (Lipunov et al., GCN5632) faint OT on the first and on the coadded images at position: aplha = dec = err = '' wich coincided with the Holland et al.(GCN Circ 5612) OT position.

Ученые МГУ и космические исследования 2009 GRB Optical-X-ray spectra power low determination The X-ray spectrum covering the time period from T+67s to T+878s is well fit by an absorbed power-law with a photon index of 2.1(+/-0.3) and column density of (2.2+/- 0.9)e21 cm**-2 (Swift, M. Perri et al., GCN 5622). They note the Galactic column density in the direction of the source is 7.3e20 cm**-2. This means that absorbtion is about 1 magnitude in our band. The optical-xray data is well fit by power-low with a photon index of during all our time observation.

Discovery of an optical flare from GRB by the MASTER robotic telescope: Possible formation of a marginally rotating black hole 2008AstL L The MASTER robotic telescope has obtained the first optical images of GRB We have discovered an optical flare from GRB , a recurrent brightening that closely follows its behavior in the X-ray range. We have determined the spectral slope for GRB from the X-ray to optical range in the first minutes. Based on the spinar model, we show that the parameters of the optical and X-ray flares suggest that the gamma-ray burst resulted from the core collapse of a 7 M star with an initial effective Kerr parameter of 7.6 and an initial magnetic-to-gravitational energy ratio of Ученые МГУ и космические исследования 2009

THE SHORT BURST GRB A SOFT GAMMA-RAY REPEATER IN THE GALAXY M81? MASTER robotic system ( responded to GRB (GRB_TIME is :25:43.785, S. Golenetskii et al., GCN4197) at several minutes after GCN Circ4197 time (GCN4198). The first image (6 square degrees) was at :55:47 UT, 2 days 10:30: after the GRB time. We have 36 images with total exposition 1080 s between 19:55: :45:17 on 6 square degrees area. The robot not find OT-candidate in IPN error box. Ученые МГУ и космические исследования 2009
