The location of the soft gamma repeater SGR 1900+14 was recently reduced to two ~5 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 G42.8+0.6. A quiescent, steady, point X-ray source was found at α(2000) = 19h07m1415, δ(2000) = 9°19'1906, whose unabsorbed flux is 3 × 10-12 ergs cm-2 s-1. 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, and have obtained upper limits to the extreme ultraviolet flux of this object using the Extreme-Ultraviolet Explorer.
