TITLE: GCN GRB OBSERVATION REPORT NUMBER: 180 SUBJECT: radio observations of GRB 981226 DATE: 98/12/29 23:20:35 GMT FROM: Dale A. Frail at NRAO D. A. Frail (NRAO), and S. R. Kulkarni (Caltech) report on behalf of a larger NRAO/Caltech collaboration: "We have observed the X-ray source (GCN #178) in the error box of GRB 981226 (GCN #174) with the Very Large Array (VLA) at 4.86 GHz on Dec. 27.00 UT and at 8.46 GHz on Dec 29.92 UT. No sources are visible within the region bounded by the NFI error circle above a 4-sigma level of 148 microJy (4.86 GHz) and 108 microJy (8.46 GHz) on these two days. In particular, we find no radio counterparts to the two optical objects noted by Galama et al. (GCN #172) and Castro-Tirado et al. (GCN #173)." This message is citeable.
