Several groups have been involved in recent years in making ultraviolet observations of planetary nebulae from rockets and satellites. About 30 or 40 nebulae have been measured up to the present, some with reasonably high spectral resolution, more with band pass filters of 100 Å or more in width. All measurements have large diaphragms (or slitless systems) so that usually the nebula and the central star are observed together (there are large nebulae for which this is not true). The photometric accuracy of the later observations is quite good, usually better than 20%.
