OT: The space weather is going to be interesting for the next few days

There is a neat chronograph video of the CMEs at this link today.


Thanks for the heads up.

Gosh but I love space weather, even if it is potentially dangerous stuff. Like tornadoes, so damn pretty.

A few minutes ago I received this alert via email.

Space Weather Message Code: ALTK09
Serial Number: 6
Issue Time: 2024 May 10 2334 UTC

Threshold Reached: 2024 May 10 2254 UTC
Synoptic Period: 2100-2400 UTC

Active Warning: Yes
NOAA Scale: G5 - Extreme

NOAA Space Weather Scale descriptions can be found at

Potential Impacts: Area of impact primarily poleward of 40 degrees Geomagnetic Latitude. Induced Currents - Widespread voltage control problems and protective system problems may occur; some power grid systems may experience component failures or protective device trips resulting in blackouts or disruption of service. Pipeline currents can reach hundreds of amps. Spacecraft - Systems may experience anomalies to include: extensive surface charging, unexpected orientation and attitude changes, uplink/downlink errors, and satellite orbit degradation. Navigation - Satellite navigation (GPS) may be degraded or unavailable for days. Radio - HF (high frequency) radio propagation may be impossible in many areas for one to two days. Aurora - Aurora may be seen as low as Florida to southern Texas and southern California.


Here’s what it looked like in Knoxville last night:

Unfortunately these are from a friend. I forgot all about it and was asleep. I’ve set an alarm for tonight; the show is supposed to continue through the weekend. Clouds willing, of course.

We had clouds. The sky is supposed to be mostly clear tonight, but even with a clear sky the trees around us might block the aurora if it is low in the sky. We’ll see or maybe not.
