**** FIRST SOLAR CYCLE 24 POLARITY SUNSPOT OBSERVED ****

The first sunspot region with Solar Cycle 24 polarity was numbered by the Space Weather Prediction Center on January 4 at 2000 UTC (3:00 P.M. EST). The sunspot region was officially numbered as 10981.

This does not mean the new cycle has officially started; however, this is a clear sign Solar Cycle 24 is within sight. Sunspots are tracked because they indicate the level of space weather activity we expect. Solar activity is forecast to reach a peak in 2011 or 2012.

Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions. More information is available at SWPC's Web site http://swpc.noaa.gov
