[CQ-Contest] Sunspots

[Jack Brindle]

And then back to zero. It is far better than that. The sunspot that  
was identified was located at 24 degrees latitude, with a reversed  
polarity, meaning it was a cycle 24 spot! Progress.

Remember, the SSN is given in groups - The tens digit means there was  
one group, while the ones digit is the count of spots within that  
group. So even if there is just one identifiable spot, it will have  
an SSN of 11. Apparently NOAA was able to pick out two individual  
spots within that one group before it disappeared.

There is lots more information around, look at spaceweather.com for  
more info. There is a pretty good site tracking the new cycle's  
progress. It is:
solarcycle24.com.
