摘要：
The location of the soft gamma repeater SGR 1900+14 was recently reduced to two similar to 5 arcmin(2) 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 alpha(2000) = 19(h)07(m)14(s).15, delta(2000) = 9 degrees 19'19 ''.06, whose unabsorbed flux is 3 x 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,(1) and have obtained upper limits to the extreme ultraviolet flux of this object using the Extreme-Ultraviolet Explorer.
