Abstract

The location of the soft gamma repeater SGR 1900ϩ14 was recently reduced to two 15 arcmin2 alternate error boxes by the network synthesis method. We have used the ROSAT High Resolution Imager to observe the error box that is closest to the supernova remnant G42.8ϩ0.6. A quiescent, steady, point X-ray source was found at ␣(2000) ϭ 19h07m14!15, ␦(2000) ϭ 9Њ19Ј19"06, whose unabsorbed flux is 3 ϫ 10Ϫ12 ergs cmϪ2 sϪ1. Its position is also consistent with a peculiar double infrared source described in a companion paper. We have also examined this region using the VLA,1 and have obtained upper limits to the extreme ultraviolet flux of this object using the Extreme-Ultraviolet Explorer.
