Bloom (Caltech) report on behalf of the Caltech-NRAO-CARA\nGRB collaboration:\n \n\"We have observed the error box of GRB000607 (GCN #693) with the VLA\nat 1.43 and 4.86 GHz on three occasions: May 8.59, May 8.79, and May\n9.79. Within this error box there are three previously known radio\nsources, cataloged by the NRAO VLA Sky Survey (NVSS) in 1993 (see\nhttp://www.cv.nrao.edu/~jcondon/nvss.html). We see no evidence for\nsignificant flux variability for any of these sources over our\nobserving time. No new radio sources were detected in the error box to\ntypical levels of 0.5 mJy (4.5-sigma) at 1.43 GHz and 0.37 mJy\n(5-sigma) at 4.86 GHz.\"\n \nThis message may be cited.",
