Details:
On April 18/19, 2026. STEVE showed up! This was from southern Alberta.
About midnight the aurora peaked at Kp5 and filled the northern sky with vertical rays and beams and a bright arc to the north, as shown in one photo taken looking north. The aurora faded and retreated north, the usual cue for STEVE to put in an appearance.
About 12:30 am there he was in his usual colours to the south – as an arc of mauve with green picket fence fingers below, and a whitish component. To the eye he looked like just a whitish arc, not obvious as STEVE until the camera revealed his characteristic colours.
STEVE = Strong Thermal Emission Velocity Enhancement, and is not a normal aurora but is hot gas flowing east-west, not from electrons raining down vertically. STEVE lasted about 30 minutes but was faint and visible only to the camera for most of that time.
