“Sunspot region 4366 produced the most powerful flare of 2026 on Monday, unleashing an X8.1 and associated coronal mass ejection (CME)—a massive explosion of plasma and magnetic field from the Sun’s outer atmosphere.“

Probably more to come, since 4366 just came into view a week ago

I monitor this stuff on NOAA's SWPC page fairly regularly - some of my partner's work has some vulnerabilities, so she usually does more of a HD backup if I give a heads-up. It's not great to have a mini Carrington Event catch you with your pants down. There's a lot of infrastructure that's not well shielded for a direct CME hit. SWPC isn't showing anything problematic, so far, but there could be some auroral displays tonight if anyone lives in Scandinavia or N Canada/Alaska.

I’ve got a space weather app that alerts me to flares and CMEs and whenever Kp hits a certain threshold. Seen a couple of aurorae because of the alerts.

A YouTube video is claiming that an atmospheric interaction with the CMEs could be heard on the 19 meter band at 15.140mhz. I have been monitoring this frequency on occasion over the last 2 weeks and have heard a random static noise of varying intensity, almost like waves crashing on a beach which sometimes is not present. I am suspicious it is not from the CME as the sound is very specific to that frequency, almost like a navigation beacon such as loran. Does anyone know if the 15.140 mhz signal is due to the CME or some generated source?

I am in no way an expert on this subject but it seems to me that CME's are not that specific. When we used to have "rabbit ears"
(antennae) on the TV, if one channel was being affected, all were.

yes, I don't think it is a natural occurrence as to the narrow bandwidth of the carrier, perhaps it is a jamming signal, and on one occasion I heard a Spanish language interview between a female and male participant.
