TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1257 SUBJECT: GRB020127: Further VLA Observations of Possible Counterparts DATE: 02/02/22 23:53:21 GMT FROM: Derek Fox at CIT Derek W. Fox and Edo Berger (Caltech), with Dale A. Frail (Caltech/NRAO), report on behalf of the Caltech-NRAO-CARA GRB collaboration: "On Feb 16.2 UT and Feb 22.0 UT we re-observed the position of Source A14 of GCN 1249 with the VLA. Three-sigma upper limits on the flux density of any 8.5 GHz source on these two dates are 110 uJy and 150 uJy, respectively. In particular, the previously identified 157 +/- 43 uJy radio source at (J2000) RA 08:15:01.4183(2), Dec +36:46:33.43(3) (GCN 1250) is not detected at either epoch. Without a confirming detection of this source, we cannot exclude the possibility that the original Feb 14.2 UT detection was spurious. On Feb 22.0 UT we also observed the regions surrounding Sources A45 and A7 of GCN 1249. Three-sigma upper limits on the 8.5 GHz flux density of any radio sources on this date are 150 uJy for each of these regions."
