TITLE: GCN CIRCULAR NUMBER: 5909 SUBJECT: GRB061201, VLT optical decay: correction DATE: 06/12/12 15:00:46 GMT FROM: Paolo D'Avanzo at INAF-OAB P. D'Avanzo (INAF-OABr & Univ. Insubria) and S. Piranomonte (INAF-OAR) report on behalf of the MISTICI collaboration: A careful inspection and re-analysis of our VLT I-band images of the short GRB061201 (D'Avanzo & Piranomonte, GCN 5896) reveals that in our second epoch of observations (carried out 1.379 days after the burst) no object is clearly visible at the position of the optical counterpart (Holland et al. GCN 5883, Haislip et al. GCN 5895, D'Avanzo et al. GCN 5884) down to I > 23.6 mag (3sigma confidence level). So, with respect to our first epoch of observation (D'Avanzo et al. GCN 5884) the afterglow clearly faded, but we can only constrain the decay index to be > 0.8. This message can be cited.
