TITLE: GCN GRB OBSERVATION REPORT NUMBER: 469 SUBJECT: GRB991216, infrared observations DATE: 99/12/17 07:03:41 GMT FROM: Peter Garnavich at Center for Astrophysics P. Garnavich, K. Stanek, M. Garcia, S. Jha and A. Szentgyorgyi (CfA) We imaged a 15'x15' field centered at the RXTE localization of the GRB991216 (T.Takeshima et al.) with the FLWO 1.2m telescope and IR Camera on Dec 17.23. We find one object in our images that is not on the digitized sky survey. The object is stellar with a J magnitude of approximately 17. The position based on the Guide Star Catalog is 05:09:24.29 11:10:39 (2000). From the difference in color between the DSS and the J-band, this may be an extremely red star and we are monitoring it to look for variability. Shorter wavelength observations are suggested.
