Interesting that the actual sunspot count reported now
is 330 sunspots.  However,  the SEC reports of the
propagation "effective"  sunspot count,  which relates
to the solar flux usually,  is now "only" 75 spots for the
last six hours,  and only about 55 spots for the last 24
hours!  Also the reported flux is now 266 per Penticton 
Observatory, but the effective flux is only 123.....?

So how come this great difference.  Well the effective
numbers come from actual Ionosphere soundings at
several locations about the world,  see this SEC site
for the info and numbers:

I have no idea why the actual ionosphere probes
report back such low propagation conditions,  UNLESS
the Penticton 2800 MHz flux is rather meaningless given the 
stormy ionosphere conditions; K index is now reported by 
SEC as an 8 .
