Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...

MODELLING OF SPECTRA OF GRB HOST GALAXIES A. Moskvitin, E.Sonbas The method of estimation of internal extinction, mass and age of host galaxies is demonstrated for three galaxies: GRB 980703, GRB 000210 and GRB 060218. The method of two-component modeling was applied: the theoretical spectrum is the sum of the spectrum of the burst component and the spectrum of the old stellar population which determines the galaxy age. ... In other galaxies the internal extinction turned out to be low. ...
