From #SolarHam - Progression of new #Sunspot #AR4366 (not yet Earth-facing, but will be soon):
"Sunspot Watch
January 31, 2026 @ 04:15 UTC
Newly assigned sunspot region 4366 continues to gradually develop as it turns into view in the northeast quadrant. It is currently producing minor C-Class flares and it is likely now a threat for a moderate M-Flare. Something to keep an eye on this weekend. Image by SDO/HMI.Growing Flare Threat
January 31, 2026 @ 14:50 UTC
AR 4366 continued to expand over the past 12 hours in both size and magnetic complexity. The region has a Beta-Delta magnetic configuration and is producing frequent mid level minor C-Flares. A moderate M-Flare will remain possible on Saturday.M6.6 Solar Flare
February 1, 2026 @ 10:40 UTC
Solar activity increases even further with an M6.6 solar flare peaking at 10:02 UTC (Feb 1). The source, AR 4366, is magnetically complex and is now a threat for an isolated X-Flare. Image below by SDO/AIA.High Solar Activity
February 1, 2026 @ 16:50 UTC (UPDATED)
What a difference a few days make on the Sun. Active sunspot region 4366 turned into a firecracker on Sunday with at least fifteen M-Class solar flares and one X-Flare (so far). Despite the brightness of these events, the mechanics have so far failed to launch any noteworthy coronal mass ejections into space and towards our planet. That could change over the next few days as the region continues to develop and currently sports a Beta-Gamma-Delta magnetic configuration. More solar flares including another X-Flare will remain possible.[And today...]
Impulsive X8.1 Solar Flare
February 2, 2026 @ 00:10 UTC
An impulsive X8.1 solar flare was just detected peaking at 23:57 UTC (Feb 1). This is the second strongest flare in terms of peak X-Ray flux of the current solar cycle. Although a bright flare, new imagery suggests that if a CME is associated, it will likely be fairly mild. Stay tuned to SolarHam where you will get the most up to date and accurate information regarding this space weather event."#SolarFlares #SolarCycle25 #KesslerEffect #KesslerSyndrome #XClassFlares

Not one to shy away from a challenge; not going to let a somewhat dismal #spaceweather #spacewx forecast hinder my #amateurradio #hamradio #pota #parksontheair activation this morning. In less than an hour made forty #qrp #morsecode contacts on 40 meters during a #solarcycle25 K5 index #geomagneticstorm.

This month, the Sun’s 11-year activity cycle will be nearing its maximum point. ☀️
Join Dr. Sten Odenwald to learn about the solar cycle & explore activities related to solar flares, cosmic rays & astronaut hazards.
Anxious to hear Dr. Odenwald's conclusion that THIS MONTH the sun will be nearing it max point for #solarcycle25 #spaceweather #spacewx #AmateurRadio #HamRadio📅TODAY at 7 p.m. EDT

@QuadRadical So, basically, if you are able to call your phone in whatever you're using as a #FaradayCage, it's NOT going to be effective against #EMPs.
"Trefethen also points out that microwave ovens, despite their thick wires, are not perfect Faraday cages. That is because if you put your mobile phone – which communicates via microwaves – into an oven and call it, it will almost certainly ring."

@QuadRadical Here we go...
"There are some examples of Faraday cages that we use these days. Faraday cages can be quite complex or very simple, ranging from a shoebox to an entire building. Wrapping your phone in plastic and then wrapping it in aluminum foil, for example, creates a makeshift #FaradayCage."

@QuadRadical Hmmmm... That may not work... I'd say maybe wrapping stuff up in aluminum foil might provide more protection. Wrapping them in foil and put them in the microwave *might* work.
"A microwave is an electric oven that heats and cooks food by exposing it to microwave-frequency electromagnetic radiation. People use this to heat their foods quickly, and some are curious if microwaves can classify as an example of Faraday cages.
"This article will show you what a faraday cage is and if a microwave is considered a faraday cage.
Is a Microwave a #FaradayCage?
"Simply put, Faraday Cages disperse electrostatic charge around their perimeter. As a result, they act as a barrier to anything within them.
"In this regard, they are a hollow conductor in which the electromagnetic charge remains only on the cage’s external surface. But, as with many things, the reality is a little more complicated.
"Microwave ovens are another common application for Faraday Cages. However, unlike other applications, they are designed to reverse and keep the microwave radiation within the oven. You can see a portion of the cage on the microwave oven’s transparent window.
"Microwaves nowadays are not built and designed as a Faraday cage, but rather a 1/4 wave choke that effectively attenuates 2.4 GHz but not other frequencies.
However,
"A Faraday cage is from any material that conducts electricity. This cage could be wire mesh, metallic sheets, or wire coils. They can be any shape, such as a box, sphere, or cylinder, and any size, ranging from extremely small to extremely large.
"According to Florida State University, the cage’s exterior can be as simple as aluminum foil. The outer covering, or conductor, can be as thin as foil, but thickening it will provide additional protection from more powerful electric fields."

I'm not sure what's going to happen, but I plan on making sure all my electronics are turned off and disconnected, and might put some of them in a makeshift #FaradayCage until after the #CMEs hit Earth. I'd like to think utilities and such will have learned from warnings from 2013, but then again, it's the human race we're talking about. Unless there's a buck to be made, we seem to be woefully unprepared for stuff that can happen -- unfortunately...
"If a massive CME were spotted, such 3-day forecasts give us some lead time: there are some measures #ElectricUtilities could take to protect their equipment, such as quickly disconnecting #transformers. Polar flights, which travel at the highest altitudes, could be rerouted to avoid contact with damaging solar particles, and some #satellites could be switched into a #SafeMode to minimize damage. Here on Earth, at the very least, we’d have some time to prepare for potential power #blackouts and other problems."
