We will report on Very Large Array (VLA) observations toward GRB 000607, the first short-duration gamma ray burst to be localized well enough to search for afterglow emission. Ulysses, Konus Wind, and NEAR all detected this burst, and its duration was determined by Ulysses to be less than 150 milliseconds. GRB 000607 belongs in the class of short duration bursts, whose progenitors are thought to be different than those of the long duration bursts. We will present the results of these VLA measurements which were taken betwen 1.4 and 8.5 GHz, over a period of approximately 8 weeks, beginning 36 hours after the burst detection.
