Initial observations with the Solwind coronagraph

Since 1979 March 28 a new NRL coronagraph called ''Solwind'' has been observing the Sun's outer corona (2.6--10.0 R/sub sun/) routinely with a spatial resolution of 1'.25 and a temporal resolution of 10 minutes. These are the first satellite observations of the outer corona near the peak of a sunspot cycle, when coronal transients and high-latitude streamers are expected to be common. Coronal variations on time scales from 10 minutes to 27 days are revealed dramatically in easily constructed gray-scale difference images.
