Since March 28, 1979, the Solwind coronagraph has been observing the Sun's white light corona (2.6 − 10.0 R⊙) routinely with a spatial resolution of approximately 1.25 arc min and a repetition rate of 10 minutes during the one-hour sunlit portion of each 97-minute satellite orbital period. 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 common.
