SC24: Sunspots appear in both hemispheres
Just when I thought we’d get to watch a single sunspot make its weary way across the surface of the Sun, a new sunspot group appears in the Northern Hemisphere. We haven’t seen a sight like this in a long time
Of course the Sun has surprised us before – one swallow not making a summer and all of that jazz – but I remain cautiously optimistic. It will be interesting to see if the new Northern Hemisphere spots last for at least a few days.
Boy, am I a glutton for punishment.

Is there an official, I’m not sure of the terminology, start of solar cycle 24? When is the cutoff between 23 and 24?
I see the excellent graph on the site below and it seems the minimum should be sometime in the 1st quarter of 2009 or maybe even April.. But the graph doesn’t distinguish 23 and 24 sunspots.
