... The cosmic gamma-ray bursts lasting more than 2 seconds (long GRBs, 2-100 sec) are now thought to be related to explosions of massive supernovae (SNe). ... The earliest spectra were obtained with the BTA of an optical transient (OT) related to the gamma-ray burst GRB 030329. ... An extended object (a blue host galaxy of gamma-ray burst with B=24.55, V=24.35, Rc=24.36, Ic=23.79) was detected which coincides with the position of an Optical transient (OT GRB) of this burst observed in October 2002. ...
