Since we're starting to move out into the new Solar Cycle, I'm starting to pay a lot more attention to the fundamentals about how sunspots are measured and finding some sites about it.

A cool site I was directed to was VE3EN's Solar Cycle 24 site with all things consolidated down to a single page. Here's  snippet of the thumbprint pics on the site:

The site updates every 2-minutes and has been around now for about a year.

Any other great sites out there?
