Precise Interplanetary Network Localization of a New Soft Gamma Repeater, SGR1627-41
Abstract
We present Ulysses, KONUS-WIND, and BATSE observations of bursts from a new soft gamma repeater which was active in 1998 June and July. Triangulation of the bursts results in a ~ 1.8 degree by 16 '' error box whose area is ~ 7.6 arcminutes^2, which contains the Galactic supernova remnant G337.0-0.1. This error box intersects the position of a BeppoSAX X-ray source which is also consistent with the position of G337.0-0.1 (Woods et al. 1999), and is thought to be the quiescent counterpart to the repeater. If so, the resulting error box is ~ 2 ' by 16 '' and has an area of ~ 0.6 arcminutes^2. The error box location within the supernova remnant suggests that the neutron star has a transverse velocity of ~ 200 - 2000 km/s.
