Springtime STEVE Sightings


STEVE ( Strong Thermal Emission Velocity Enhancement ) might look like an aurora, but it’s not. STEVE is an atmospheric phenomenon characteristic of northern hemisphere spring and fall. The result of uppity solar wind messing with Earth’s magnetic field. Meddling which allows ribbons of super heated gas travelling at speeds exceeding 13,000 mph to create observable arcs of soft purple hues. STEVE favours latitudes between +50N and +55N. Go STEVE! Hope to meet you one day.
