Prompt optical observations of GRB 080330 and GRB 080413A

摘要：

We report on the results of rapid responses to GRB 080330 and GRB 080413A by the ROTSE-IIIb and ROTSE·Illc telecopes．In both cases,optical follow-up started during the prompt emission phase and recorded optical flares peakingat similar times as the last hard X-ray pulses detected by the Swift BAT．For both events,the XRT observations started atthe end of the prompt BAT detection and displayed all evolution in time opposite to the optical lightcurve．These very earlyobservations provide us an opportunity to probe the onset of afterglow for these two events．
