Those looking to the northern skies late Monday night into Tuesday morning were able to catch quite the show. The conditions were just right for the Northern Lights, otherwise known as aurora borealis, to make another appearance this year, stretching from at least Montana to Ohio to delight stargazers. According to the National Oceanic and Atmospheric Administration, the maximum Kp was six, which is strong enough for moderate storm conditions. By comparison, April’s Northern Lights, which were much more vibrant, had a Kp of 8. Kp refers to the measurement associated with the K-Index, which deals with the magnitude of the geomagnetic storms that cause the Northern Lights to occur.
