GCN Circular 3285
M. Jelinek, A. de Ugarte Postigo (IAA-CSIC Granada), P. Kubanek (ASU-CAS Ondrejov), T. J. Mateo Sanguino (Univ. de Huelva), S. Castillo, J. Gorosabel, S.Guziy and A. J. Castro-Tirado (IAA-CSIC), report: "Following the detection by SWIFT/BAT of GRB 050416B (Hullinger et al., GCN 3279), the 0.6m BOOTES-IR telescope at IAA's Observatorio de Sierra Nevada responded automatically at 23:13 UT (i.e. 38 minutes after the event). Although we are still testing the telescope during the commissioning phase, and the near-IR camera is not yet installed, an optical camera was available. A co-addition of first 20 R-band images taken at that particular instrument reveals no optical counterpart in the SWIFT/BAT error box down to R = 19. The instrument sensitivity was highly compromised due to the presence of the nearby moon. Additional info on BOOTES-IR can be found at www.iaa.csic.es/BOOTES-IR.html." This message can be quoted.
