TITLE: GCN GRB OBSERVATION REPORT NUMBER: 444 SUBJECT: GRB 991106, radio observations DATE: 99/11/10 04:51:42 GMT FROM: Dale A. Frail at NRAO D. A. Frail (NRAO) reports on behalf of a larger collaboration: "Beginning 1999 November 7.34 UT we imaged the field of GRB 991106, centered on the refined BeppoSAX position (GCN #435) with the Very Large Array (VLA). A frequency of 8.46 GHz was used, which provides a field-of-view of 5.3 arcmin to half power (FWHM). A quick-look analysis of the data shows a single unresolved source near the western edge of the WFC error circle at R.A.= 22 24 27.65, dec.=+54 21 53.0 (J2000), with conservative errors of 1 arcsec in each dimension. The probability of detecting an unrelated background source in the WFC error circle is not insignificant (~10%). Further radio observations are underway to determine whether the source is variable or not." This message is citeable.
