Abstract

The detection of a bright optical emission measured with good temporal resolution during the prompt phase makes ORB 060111B a rare event that is especially useful for constraining theories of the prompt optical emission. Comparing this burst with other GRBs with evidence of optical peaks, we find that the optical peak epoch (t(p)) is anti-correlated with the high energy burst energetic assuming an isotropic energy release (E-iso) in agreement with Liang et al. (2009), and that the steeper is the post-peak afterglow decay, the less is the agreement with the correlation. GRB 060111B is among the tatters and it does not match the correlation. The Cannonball scenario is also discussed and we find that this model cannot be excluded for GRB 060111B. (C) 2010 COSPAR. Published by Elsevier Ltd. All rights reserved.
