[South Florida DX Association] Second Solar Minimum

[Bill Marx]

Posted Saturday August 2, 2008 on http://www.kn4lf.com/kn4lf5.htm :

It appears that we are seeing a second minimum in solar cycle 23 and solar
cycle 24 may not get underway in earnest until winter 2009.

....This brings us to our practice of presenting the average daily sunspot
number for the past three months, then comparing it with a monthly 3-month
moving average for the past couple of years. There were 92 days in May, June
and July, and 70 out of those 92 days had no sunspots.  This brings us back
toward the low of 3 from last fall, centered on October. The average daily
sunspot number for the last three months, centered on June, was just
3.7.....
