Henry, P. ; Bowyer, S. ; Rapley, C. G. ; Culhane, J. L. Abstract The 3700 square degrees around the South Equatorial Pole have been surveyed using a broad-band photometer with peak response at 90 A. One source was detected at about the same intensity as HZ 43. An extrapolation of the results implies that there are about 10 extreme-ultraviolet objects over the whole sky which are as bright as HZ 43. Implications of these results for theories of white dwarf evolution are briefly discussed.
