Solar Maximum Mission Information and Data on the MLSO website

The Solar Maximum Mission (SMM) satellite was launched in 1980 aboard a NASA Delta rocket. Among SMM's primary science objectives was the study of the dynamics of solar flares and the study of solar magnetic fields associated with the flare phenomenon. Towards this end, the High Altitude Observatory (HAO) provided a white-light coronagraph/polarimeter (C/P) to study the relationship of the corona to the flare process.

Observing the Quiet Sun: A Weak Cycle Offers Opportunity for Expanding Solar Understanding

Observing the Quiet Sun

Since the dawn of the Space Age in the 1950s, solar maxima have coincided with strong upticks in sunspot activity but the current cycle, Cycle 24, which was expected to peak in Spring of 2013, has been unusually quiet.
