GCN Circular 4337
C. Guidorzi, I.A. Steele, C.J. Mottram, A. Monfardini, C.G. Mundell, A. Gomboc, R.J. Smith, M.F. Bode (Liverpool JMU) report: "The 2-m Liverpool Telescope located in La Palma, Canary Islands, observed GRB051211B detected by INTEGRAL (Mereghetti et al. GCN 4327) ~66 min after the GRB trigger time. The observation could not commence earlier because of the weather. The "detection mode" procedure did not detect any obvious candidate brighter than about r'=16 mag from 3x10-s images. The limiting magnitude is due to poor sky conditions and bright moonlight. After visual inspection of a 6-min stacked image started at ~93 min after the burst, we detect neither the optical candidate found by Klotz et al. (GCN 4328) nor any counterpart to the X-ray source reported by Swift/XRT (Pagani et al., GCN 4332), down to r'~18. The limiting magnitude is automatically calculated with respect to the USNOB1.0 'R2' values of the field objects."
