Abstract
We present Ulysses, Konus-Wind, and BATSE observations of bursts from a new soft gamma repeater that was active in 1998 June and July. Triangulation of the bursts results in a ~1.8d by 16" error box whose area is ~7.6 arcmin2 and which contains the Galactic supernova remnant G337.0-0.1. This error box intersects the position of a BeppoSAX X-ray source that is also consistent with the position of G337.0-0.1 and is thought to be the quiescent counterpart to the repeater. If so, the resulting error box is ~2'×16'' and has an area of ~0.6 arcmin2. The error box location within the supernova remnant suggests that the neutron star has a transverse velocity of ~200-2000 km s-1.
