Solar Cycle 24 forecast reduced yet again

We had a reduced forecast from NASA just a month ago and it has reduced yet again.

The peak is now expected in July 2013 but this could well slip a month or two. This Landscheidt Minimum continues to look like a Dalton Minimum.

December 2010 forecast smoothed sunspot number maximum of 64 in June 2013

January 2011 forecast smoothed sunspot number maximum of 59 in June/July 2013

February 2011

Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 58 in July of 2013. We are currently two years into Cycle 24 and the predicted size continues to fall.

The latest forecasts for sunspot number and 10.7 Radio flux and Ap progression are here: http://www.swpc.noaa.gov/SolarCycle/
