TITLE: GCN CIRCULAR NUMBER: 11632 SUBJECT: GRB 110205A: TAROT Calern observatory detection of an optical flare DATE: 11/02/05 02:47:49 GMT FROM: Alain Klotz at CESR-CNRS Klotz A. (CESR-OMP), Gendre B. (ASDC), Lass M. (UWA), Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report: We continue to acquire images the field of GRB 110205A (cf. Klotz et al. GCNC 11630). After a first peak of brightness R~16.7 at t~225s, the flux decreased at R~18 about 360s after the trigger. Then, the brightness increased dramatically and reached R~14.1 at t~1150s. Now the flux decreases slowly: R~15.0 at t~1800s.
