GCN Circular 13385
A. S�nchez-Caso (Gualba Observatory, Barcelona) and A. J. Castro-Tirado (IAA-CSIC Granada), on behalf of a larger collaboration, report: �Following the detection of GRB 120624B by Fermi/GBM, Fermi/LAT, Konus/Wind and Swift/BAT (GCNC 13377, 13378, 13379 and 13381 respectively), we have imaged the field with the 0.36m f/7 telescope at Gualba Observatory in Barcelona (Spain) starting on June 25 at 20:30 UT (i.e. about 22 hr post-burst). Within the Swift/BAT 3� radius error box no optical afterglow candidate is identified for GRB 120624B. The limiting magnitude in the 300-s unfiltered image (with the crescent moon only 9 deg away) is 18.5.� This message can be quoted.
