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.

See Southern Hemisphere.

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.
