"We report on the detection of an early rising phase of optical afterglow (OA) of a long GRB \u2009090726. We show that neither the dust nor the gaseous component of the circumburst medium underwent any evolution during the decay of this OA. We also show that this OA belongs to the least luminous ones in the phase of its power-law decay." . . . . . "\u0160trobl, Jan" . "251652" . .
