And a fantastic one occurred final evening, proven dramatically by the cameras at Greg Johnson’s Skunk Bay Climate website within the northern a part of the Kitsap Peninsula.
Here’s a video of it on your viewing pleasure.
This occasion was related to a Coronal Mass Ejection (CME) from the solar a number of days in the past, which reached earth’s orbit final evening. In consequence, the Kp geomagnetic exercise index climbed to round 5 (see plot beneath). That’s usually excessive sufficient to get an auroral show round right here. It’s nonetheless round 4.
The interplay of particles from the solar and the earth’s higher environment and magnetic discipline produces a “donut” formed areas of auroral exercise, as illustrated by the short-term forecast of what occurred final evening.
Disenchanted about lacking this celestial present?
Don’t fret, you could have one other probability quickly!
One other CME occurred and the newest NOAA Area Climate Forecast is for later tomorrow and Thursday.
Lastly, we at the moment are in Photo voltaic Cycle 25, which has turned out to be extra lively than predicted (see beneath). No surprise we’re getting some good shows from an more and more lively solar!
The crimson line is the expected.
