Auroral kilometric radiation (AKR) frequency range of about 50-500 kHz. AKR is an intense radio emission escaping outward from the earth's auroral regions at frequencies above the local electron plasma frequency.

I'm picking up some anomalies auroral hiss emissions, but never seen these before! Somewhat Like 50 teV electron beams? only different, Cern. Glad I don't have television, no radio on lately either. But I can hear a Taos like hum, and my phone went to static.

Going back to watching on my spectrogram, but getting a head ache again tonight.
