Solar Flux to Bottom Out in July as Cycle 24 Gets Closer (Jul 3, 2007) -- 
The National Oceanic and Atmospheric Administration's (NOAA) Space 
Environment Center (SEC) released their monthly forecasts of sunspot number 
and 10.7 cm radio flux, including high and low bounds to their forecasts. 
The SEC forecasts that the smoothed sunspot number reached its low value of 
11.7 in March 2007, and predicts that the solar flux will reach its low of 
75.4 this month. This is the fourth month in a row that the SEC predicts the 
solar flux will bottom out in July. Based on the SEC predictions, this is 
probably at the bottom of Cycle 23 and extremely close to the beginning of 
Cycle 24. Two events will mark the beginning of the next sunspot cycle: The 
observation of the first opposite magnetic polarity sunspots compared to 
Cycle 23 sunspot polarity, and the observation high solar latitude sunspots 
-- the Cycle 23 sunspots are now very near the solar equator. The SEC 
predictions table and sunspot number and solar flux prediction graphs are 
available on the SEC's Web site. -- The Daily DX
