The aurora borealis is one of the most spectacular phenomena that skywatchers are always keen on catching. It has colored the night sky over the past decade when the conditions in the atmosphere permit it. Skywatchers were always counting on forecasts for sightings of the majestic phenomenon.
However, according to scientists, the current condition of the atmosphere is showing signs of the decreased occurrence of the northern and southern lights. In place, a new phenomenon that is similar to the aurora borealis which also involves a spectacular display of lights is starting to frequent the night sky. They call this new phenomenon STEVE or Strong Thermal Emission Velocity Enhancement.
