Not everything that looks like the Aurora, is not. For example, February 29-Terrence cook saw these fiery luminous columns over the mountains La Sal in Utah.
This phenomenon is called light pillars and has nothing to do with space weather. They are formed when ice crystals in the atmosphere catch the light of the city lights. In this case, the light came from the city of Monticello, located at a distance of about 50 km.
Of the crystals are spread glow in colorful columns. The dominant red-orange tint, probably due to sodium lamps high pressure. Modern led bulbs cause of the blue-white shades.
The light poles at this time of year is common to Northern latitudes. Unseasonably high temperatures in the earth could melt the crystals, erasing the bottom of the columns. They also could be diluted due to the group of low clouds.
