TITLE: GCN CIRCULAR NUMBER: 16777 SUBJECT: GRB 140903A: 6 GHz VLA detection DATE: 14/09/04 22:47:57 GMT FROM: Wen-fai Fong at U of Arizona W. Fong (U. Arizona) reports: "We observed the position of the short-duration GRB 140903A (Cummings et al., GCN 16763; GCN 16765) with the Karl G. Jansky Very Large Array (VLA) beginning on 2014 Sept 4.040 UT (9.70 hr post-burst) at a mean frequency of 6 GHz. In 1 hour of observations, we detect a ~0.11 mJy radio source at the position: RA(J2000) = 15:52:03.21 Dec(J2000) = +27:36:10.7 with an uncertainty of 0.3" in each coordinate. This position is coincident with the reported optical source (Capone et al., GCN 16769; Cenko et al., GCN 16770; Cucchiara et al., 16774; Fruchter, GCN 16776). Further observations are planned. We thank the VLA staff for quickly executing these observations."
