there was some good viewing here in Arizona(phoenix), i didnt notice any other coincidences,
cb radio was un-effected but oddly the level of static was lower.

Thanx for the info !!

You're welcome. I think the bands are opening back up now but did manage to slip a few South American stations in the evening hours during the flares. They were weak. The static levels were high here during the mornings and afternoons. We didn't see the Northern Lights here due to the cloud cover.

I have been watching Tamitha Skov's YouTube for years, 90% of the time she gets her predictions right.

They are predicting a lot of fireworks from the sun in 2025.
