TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2148 SUBJECT: OT GRB 030329: early UBVRcIc spectral evolution DATE: 03/04/17 14:57:35 GMT FROM: Timur Fatkhullin at SAO RAS <timur@sao.ru> T. Fatkhullin, V. Komarova, V. Sokolov (SAO RAS), V. Kurt (ASC RAS), A. Cherepashchuk (SAI MSU), K. Postnov (SAI MSU), V. Reshetnikov (AI SPBU), Alberto J. Castro-Tirado (INTA, Madrid and IAA, Granada) report: A part of the results of the UBVRcIc observations with the 1-m (Zeiss-1000) of SAO RAS at two epochs on March, 29 and the next two nights are now presented at our anonymous FTP-site: ftp://ftp.sao.ru/pub2/grb/GRB030329/ One can see the evolution of the early broad-band UBVRI spectra. In addition, comparison with the MPFS spectra (see GCN #2142) allows us to perform more precise flux calibration of these spectral data. Sorry! More correct reference quoted in GCN #2142 is E. Grassberg, V. Imshennik and D. Nadyozhin, 1971, Astroph. Space Sci., 10, 28
