A small A sunspot group appeared today at latitude -28 degrees. This tiny feature belongs to the new solar cycle and is the first one to appear in the Southern hemisphere. No significant activity is expected from this group
Just an FYI! On Sunday 06/08/2008 the three solar flux values measured at Pentiction, BC, Canada were 64.8 64.9 64.9. The 64.8 value is the second lowest of the current solar minimum. The lowest SFI of 64.4 occurred on 09/28/2007.
Using the smoothed sunspot number solar cycle 23 minimum was in October 2007 with a value of 3.0. Looking at the values below you can see that solar cycle 24 has pretty much stalled since December 2007.
October 2007- 3.0 November 2007- 6.9 December 2007- 8.1 January 2008- 8.5 February 2008- 8.4 March 2008- 8.4 April 2008- 8.9

It is anecdotal evidence of a later and smaller solar cycle 24 peak.But what is not anecdotal evidence is a later and smaller solar cycle 24 peak due to the slowing of the Sun's internal meridional circulation (kind of like a conveyor belt) that normally moves at 1 meter per second. In the past ten years the circulation has slowed to approximately .75 meters per second in the north and .35 meters per second in the south, the slowest since the 19th century.
The Dalton Minimum was a period of low solar activity, lasting from about 1790 to 1830 . Like the Maunder Minimum and Spörer Minimum it coincided with a period of lower than average global temperatures. Low solar activity seems to be strongly correlated with global cooling.
A detailed analysis with the auroral and solar data has been given by Wilfried Schröder, N. N. Shefov in a paper in Ann. Geophys. 2004, also details can be found in Wilfried Schröder, Das Phänomen des Polarlichts (The aurora in time), Darmstadt, Wissenschaftliche Buchgeselllschaft 1984 and Science Edition, Bremen, 2000.
