Neutron stars were not expected to be observable in the extreme ultraviolet and hence their detection in this band is a surprise. More important is that EUV observations provide unique new information on these objects. In the accompanying Table 1, I list the neutron stars detected in the EUV with the Extreme Ultraviolet Explorer (EUVE). The binary object Her X-l is the only object detected in the all sky survey. This is not surprising since it is the only neutron star system with sufficient intensity to be detectable in the 500 to 2000 second sky intergrations which are typical for the EUVE all sky survey. All the neutron stars were detected in the 100 Å (Lexan) bandpass. A more complete description of EUVE and the all sky survey are provided in Bowyer and Malina (1991), and in Bowyer et al. (1994).
