TITLE: GCN GRB OBSERVATION REPORT NUMBER: 97 SUBJECT: SGR 1900+14 DATE: 98/06/05 00:43:43 GMT FROM: Josh Bloom at CIT SGR 1900+14 IR Observations B. R. Oppenheimer, J. S. Bloom, S. S. Eikenberry, and K. Matthews (Caltech) report: "We have obtained narrowband 2.2 micron images of the proposed infrared counterpart to SGR 1900+14 (Vrba et al. 1996, Ap.J. 468, 225) at June 3.486 UT, 4.1 days after the recent bursting activity reported by Hurley et al. and Kouveliotou et al. (IAUC 6929). Differential photometry of stars "A" and "B" (the double M -stars) and star "C" of Vrba et al. show A-B=0.4 +-0.1 mag and A-C=4.5+-0.2 mag, consistent with the measurements of Vrba et al. Over the course of 10 minutes (ten separate frames) no variability was detected in the double M-stars to a limit of 0.1 mag." This report may be cited.
