Solar Cycle 24 August Update

Solar Cycle 24 August Sunspot and Solar Flux data continues to paint a picture of a much less active Sun when compared against the previous Cycle 23.

First, David Hathaway’s September edition of his sunspot predictions. Hathaway has a mid, high and low range chart with the actual data slightly below the mid-range forecast.  The Hathaway midrange predicts a maximum monthly high of about 70 Sunspots in early 2013.   Cycle 23 experienced a maximum monthly high of about 120 in 2001.

NOAA  sunspot prediction chart has only a single line which predicts a maximum monthly of about 90 sunspots.    It is shown below:

Solar flux through August appears to be trending below the NOAA prediction for Cycle 24.  The NOAA Cycle 24 solar flux prediction is for a peak of 140 in 2013.   This contrasts with  the Cycle 23 maximum of about 195 in 2002.    See the NOAA chart below:
