#AmateurRadio #hamradio operators, here's the #SolarCycle25 #Spaceweather #Spacewx forecast for the North American CW QSO Party #NorthAmericanCWQSOParty this weekend. #CW #MorseCode #SolarFlare #Solarflares #Radioblackouts #RadioBlackout
R1-R2 (Minor - Moderate) level solar flares continue to be expected into the weekend (1 - 4 August). There is also a continuing chance for an R3 (Strong) event. Details at

The latest #Spaceweather update from Spaceweather.com
"Because the sunspot is behind the edge of the solar disk, the flare was partially #eclipsed. It was probably even stronger than it appeared. 'X8.7' is almost certainly an underestimate of the flare's true strength.
"Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave #RadioBlackout over the Americas. Ham radio operators, aviators and mariners may have noticed a sudden loss of signal at all frequencies below 30 MHz.
"Subatomic debris from this event might soon reach Earth, guided toward our planet by the #ParkerSpiral. Also, a #CME might be in the offing. Stay tuned for updates!
"EARTH IS CONNECTED TO SUNSPOT AR3664: Giant sunspot AR3664 is no longer facing Earth. That makes it extra dangerous. The #Carrington-class sunspot is passing over the sun's western limb--a region of the sun that is magnetically connected to our planet. Indeed, we are feeling the effects of that connection right now.
"What's causing this? Protons accelerated by solar flares in the magnetic canopy of #AR3664 are following the #ParkerSpiral back to Earth. Think of it as a magnetic superhighway. The arriving particles are funneled by our planet's magnetic field toward the poles where they ionize the atmosphere and interfere with the normal transmission of shortwave radio."

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."

"Earth Directed Halo #CME / #RadiationStorm
March 23, 2024 @ 10:30 UTC
"LASCO coronagraph imagery is updated and shows a full halo coronal mass ejection (CME) that is Earth directed. The main bulk of plasma seems to be heading north, however a noteworthy impact past our planet is likely within 72 hours and may trigger a geomagnetic storm once it arrives. Energetic particles did begin to reach our planet almost 3 hours after the flare event and a minor (S1) to moderate (S2) radiation storm is currently in progress."
