Can You Say Radio Blackout?

 Youch! Haven't seen things this squirrelly in quite a while:

 

Radio propagation in the 3~30MHz range is pretty bad tonight.

Anywhoo....Back to the Basement! where the Fisher receiver is showing positive signs of life.....

  1. Looks like a severe geomagnetic storm is underway according to spaceweather.com. If it's clear, look for auroras this evening. Some are being seen as far south as Nebraska.

    1. You can see the Aurora here. Not very bright in town, but go a few miles North and it's spectacular.

    1. A Coronal Mass Ejection. Like a flare, but bigger.

  3. OTOH, 30m seemed good last night around here and I even snagged a new country on 30, Algeria. That was around 0245 UTC. That was around the peak of the storm.

    The Kp (4 hour average) peaked at 00 to 0300 UTC last night, according to the NOAA site:

    I read in the local newspaper that red skies were visible around here last night. Last time that happened was in cycle 23 (!) which I missed as well.

    1. I don't recall ever working Algeria. Nice catch! Anything on six down your way?

    1. Which is caused by the energetic particles that blew out of the Sun..

    2. And the particles, and UV radiation from the Sun, "charge up" the different layers of the Ionosphere, which makes them either reflect (GOOD!) or absorb (BAD!) radio energy at various frequencies.

Keep it civil, please....

Happy Thanksgiving!

  We're headed up to the in-laws in Cheyenne for the day. Hope you all have a Happy Thanksgiving.
