TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5261 SUBJECT: GRB 060614: optical observations DATE: 06/06/15 16:22:59 GMT FROM: Daniele Malesani at SISSA-ISAS,Trieste,Italy D. Malesani (SISSA), S. Covino, S. Campana, D. Fugazza, G. Tagliaferri (INAF/OABr), G. Chincarini (Univ. Milano-Bicocca), and L. Stella (INAF/OAR), report on behalf of the MISTICI collaboration: We have observed the afterglow of GRB 060614 (Parsons et al., GCN 5252) with the ESO VLT-UT1 equipped with the FORS2 instrument. The optical afterglow is well detected in the R filter, and shows a dimming by 0.45+-0.03 mag between 14.4 and 21.6 hr after the GRB. Assuming a power-law decay, this corresponds to a decay slope alpha ~ 1, consistent with what found by French et al. (GCN 5257). Compared with several nearby USNO-B1 stars (R1 magnitudes), the afterglow has R~19.3 on Jun 14.12892, with a calibration uncertainty of ~0.2 mag. We note an overall similarity between the early optical light curves of GRB 060614 and GRB 060218 (Campana et al., astro-ph/0603279), both presenting a maximum ~0.5 d after the burst. GRB 060614 is however peaking earlier. We encourage further follow-up of this interesting event. We acknowledge excellent support from the ESO staff at Paranal, in particular Rachel Gilmour and Leonardo Vanzi.
