             How to Look for Auroras
            
            
            Where are auroras expected right now? Look for yellow or
                    red on the map below —these are the most likely zones.
                    (The light blue zone shows only the range over which data
                    was taken and does not indicate likely aurora zones.) Keep
                    in mind that auroras can only be seen at night. The red arrow
                    shows the current location of high noon.

            Also check another predictive indicator known as the planetary
            
             K-index,
                    or Kp
            
            . This number from 0 to 9 measures geomagnetic
                    activity over the latest three-hour period. A Kp index of
                5 or more means that aurora sightings are more likely.
