Bower (UC  \nBerkeley) report on behalf of a large collaboration:\n\n\"Using the Allen Telescope Array (ATA, http://ral.berkeley.edu/ata/),  \nwe observed GRB 070612A (Grupe et al., GCN 6509) at 1.4 GHz on 2007  \nJune 16 UT and at 5 GHz on 2007 June 17 UT. The observations made use  \nof 8 antennas outfitted with dual-polarization receivers. At the  \nlocation of the optical afterglow (Updike et al., GCN 6515), we   \nobtained 3-sigma limits of 50 mJy at 1.4 GHz and 10 mJy at 5 GHz for  \nthe flux density of GRB 070612A at these epochs.  The data were  \ncalibrated versus the QSS 0927+392. At L-band the 8 brightest NVSS  \nwere measured to be located within 10% of the synthesized beamwidth  \nand 100 mJy of the NVSS flux densities. The limits reported herein  \nare consistent with the tentative WSRT detection at 4.9 GHz (Horst et  \nal. GCNs 6549, 6576).\n\nA 42-antenna ATA is currently being commissioned.\"\n\nThis message may be cited.",
