Today's 1700/2000/2300 UTC solar flux index readings were as follows; 64.2
64.6 64.6. The 64.2 reading is the lowest of solar cycle 23 and the lowest
since the 64.5 which occurred on July 18, 1996 at the bottom of solar cycle
22. From memory (and it may be incorrect) the 64.2 is the lowest SFI ever
measured.
On July 11, 2008 NASA solar physicist David Hathaway published an article
http://science.nasa.gov/headlines/y2008/11jul_solarcycleupdate.htm stating
that the length of the current lull between solar cycle 23 and 24 is within
the realm of normalcy. With all due respect I think that he missing the
forest for the trees. The real issue is that the length of solar cycle 23,
from it's first visible spot in May 1996 through the most recent one now is
12.4 years, which is the longest recorded solar cycle in recorded history.
The current lull may last into winter 2009.
