The Northern Lights (aurora borealis) are perhaps the thrill of the summer for the Black Oak Lake night sky watcher. They generate a number of very late night phone calls around the lake which infuriate your neighbors until they go out and look up! The dancing lights are caused by variations in the “Solar Wind” emanating from the sun. The sun goes through a cycle of activity which averages 10.7 years long. These cycles are numbered and we are currently (January 2022) just beginning solar cycle 25 and are at a low level of activity. For daily updates on solar activity see www.solarcycle24.com.
Over recorded history the intensity of a late starting cycle has been less than normal so we may be in for a couple of decades of below normal solar activity. History has also shown that earth’s temperature varies with solar activity (see http://home.cern/about/experiments/cloud) so we may also be in for a return to below normal cold.
YOU CAN FORECAST THE NORTHERN LIGHTS ….. SORT OF
Since the solar wind takes from 17 hours to 7 days to reach earth, the aurora borealis is somewhat predictable. Satellites positioned at the L1 Lagrange Point (FYI, the L2 Lagrange Point is the new home of the James Webb Space Telescope which arrived there on Feb 5, 2022) of equal gravitational attraction between the sun and the earth can give up to 48 hour warnings of an approaching Coronal Emission.
