“Both NOAA and SOHO coronagraphs have detected a full halo storm cloud heading directly for Earth. NASA and NOAA models agree that the #CME will arrive Dec. 9th:”
“The impact could spark G2 (Moderate) to G3 (Strong) category geomagnetic storms. Mid-latitude auroras mixed with moonlight are possible if the storm reaches the upper end of this range. "
🚨 THE WRONG SUNSPOT KEEPS ERUPTING 🚨
While everyone’s watching monster AR4294–4296, the real action came from AR4299 on Dec. 6, firing an almost X-class M8 flare and launching a CME straight at Earth. A full-halo CME is inbound, with NASA eyeing a Dec. 9th arrival and possible G2–G3 geomagnetic storms. Mid-latitude auroras? On the menu.

Somebody correct me if I'm wrong, but the aftermath of the October 2003 solar storm (by which I mean most people never even knew anything had happened) seems to suggest that modern technology has already survived a #Carrington -level event and can presumably survive another one.

So why is everybody saying that big #sunspot is going to cause the end of the world as we know it? 😵💫 I'm confused and kinda freaked out.
In the words of spaceweather.com, this is a sunspot about which "[e]ven Richard Carrington would be impressed."

Aber gerade ziemlich was los, in unserer aktuell 147 Millionen Kilometer entfernten Zentrale.

Golden Mr. Sun
Please don’t Carrington on Me.

Managed to find some thinner clouds this afternoon to photo the monster sunspot groups (from l to r: 4296, 4294, and 4298) on our star today. Shot from West Seattle w/Canon 80D, 600mm lens with no solar filter.

The #sun right now, with my 60(!)mm DSLR lens. Plus neutral density filter. At 1/4000s and aperture 22 and ISO100...
Even there the #sunspot-group is clearly visible 😬
Pictures later but Holy Moly! That #sunspot group is MASSIVE. If have the opportunity, do take look.
The #sunspot show goes on: now activity region (1)4274 - which caused a major geostorm last month - has returned onto the disk with the new number (1)4299. And immediately fired off an X1.9 #SolarFlare today: see https://www.spaceweatherlive.com/en/news/view/596/20251201-x1-9-solar-flare.html and https://www.facebook.com/photo/?fbid=1255308929956301 for updates of the situation, also regarding the big group (1)4294. This is a crop from an #SDO HMI image - https://jsoc1.stanford.edu/data/hmi/images/latest/HMI_latest_Int_4096x4096.gif - of 18:11 UTC, i.e. exactly an hour ago.
🌞 GIANT SUNSPOT ALERT! A massive sunspot group—one of the biggest of Solar Cycle 25—is rotating into view. It spans ~130,000 km, and several of its dark cores are larger than Earth, making it an easy target for backyard scopes. It fired an M6 flare on Nov. 28, likely even stronger since it was partly hidden. Now that it’s facing Earth, future flares will be geoeffective. Full story at https://spaceweather.com

@solownh i dunno it says right there in the bible that "thou shalt bomb the middle east whenever there is a solar flare"
