Wednesday 25 May 2022: Possible Aurora?

While reviewing the Space Weather Enthusiasts Dashboard at the NOAA Space Weather Prediction Center, I noted that the kp-index numbers are climbing to 4. This starts at 1800h UTC on 26 May and continues to 27 May 0900h UTC. If I’m doing my math right, we add 4 hours to those times. Therefore, look north starting 10:00 PM Thu 26 May. If there are no clouds, you might see a glow or spires off above the northern horizon. If not sure you’re seeing aurora, shoot with your tripod-mounted camera a 15 or 30 second exposure and look for green.

And then, over at I saw a note about possible noctilucent clouds. So watch for those before dawn or after sunset.

The Astronomer-In-Residence program is coordinated by the Allan I Carswell Observatory (AICO) at York University with the Killarney Provincial Park Observatory (KPPO).
