  "body": "P. Garnavich (Notre Dame), J. L. Prieto, R. Pogge (OSU) report:\n\nWe observed the position of GRB 080310 (Chornock et al. GCN 7381;\nCummings et al., GCN 7382) with the Large Binocular Telescope and\nLBC red and blue cameras on March 11 starting at 11:30 (UT) or 26.8\nhours after the burst. On the red camera the images were taken\nthrough a Sloan-r filter and calibrating with the SDSS catalog\n(Cool et al.; GCN 7396) we find the brightness to be r=21.38+/-0.05 mag.\n\nExtrapolating the decay from LBT observations of March 10 (Prieto\net al., GCN 7392) with an index of 1.15, the afterglow is about\n0.2 mag brighter than expected. This could be due to host galaxy\nlight or deviations from a single power-law decay.\n\nThe LBT is an international collaboration among institutions in the\nUnited States, Italy and Germany. The LBT Corporation partners are:\n*  The University of Arizona on behalf of the Arizona university system\n*  Istituto Nazionale di Astrofisica, Italy\n*  LBT Beteiligungsgesellschaft, Germany, representing the Max Planck\nSociety, the Astrophysical Institute Potsdam, and Heidelberg University\n*  The Ohio State University\n*  The Research Corporation, on behalf of The University of Notre Dame,\nUniversity of Minnesota and University of Virginia\n\nThis message may be cited."
