Solar Update June 2017–the sun is slumping and headed even lower

by David Archibald, June 6, 2017 in WUWT


Solar cycle 24 has seen very low solar activity thus far, likely the lowest in 100 years. The F10.7 flux shows that over the last three and a half years the Sun has gone from solar maximum through a bounded decline to the current stage of the trail to minimum. Solar minimum is likely to be still three years away.
