EUV and Soft X-ray Observations of Gamma-Ray Burst Sources

The 3rd Interplanetary Network of gamma-ray burst detectors has produced some of the smallest GRB error boxes ever available for deep counterpart searches. A 40 ksec EUVE observation of the March 25 1992 source region was carried out on August 25/6 1993. We have summed the spectral channels to use the three spectrometers as broad-band photometers, and achieve sensitivities in the 10(-14) erg cm(-2) s(-1) range. We discuss the results of this search in a hitherto unexplored wavelength range. A 40 ksec ROSAT PSPC observation of the May 1 1992 source region is scheduled for October/November 1993. The error box of this GRB contains a weak (10(-13) erg cm({-) 2}s(-1) ) X-ray source which was discovered in a 2700 s TOO observation. We will discuss the spectrum and variability of this source, and its possible relation to the burst source.
