Infra-Red, Soft Gamma-Ray Repeaters

Scientific paper

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. (ATEL #23, #24; 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.
