NOAA Auroral Activity add-on released

The auroral oval represented in the plots is not a photograph, and is not real-time. It is extrapolated statistically from the Space Environment Monitor (SEM) auroral particle data obtained during a single pass of a POES satellite over a polar region. For more information, see the NOAA POES Auroral Activity site (http://www.sec.noaa.gov/pmap/index.html).

See the Auroral Activity Extrapolated from NOAA POES Satellites add-on page for more details.
