The new #SpaceWeatherWoman forecast is up! See the sunspots on the Sun's farside that will soon give us another round of big flares, Earth-directed solar storms & lots of radio noise! Activity could climb fast. Aurora possibilities high over the next two weeks https://www.patreon.com/posts/144547128
The big X-flare yesterday manifested in a two-part eruption, which is proving tough to model. As such, NOAA & NASA predictions are different. Both are shown. Note the NASA run has both "shock" and "bulk" runs superposed in a single composite. For details see https://www.patreon.com/posts/144874021

Very intense #solarstorm launch underway from old Region 4274 (likely to be renamed 4297). This storm is not Earth-directed (it is directed towards Saturn), but I would not be surprised if we see a radiation storm rise at Earth over the next few hours.

X-1.95 flare now! Although not yet completely in view, old Region 4274 it is firing big flares again! This one is causing an R3 Radio blackout on the dayside of Earth now! Expect VHF/HF radio degradation over next hour, especially in the Asian Pacific (colored regions in map).

Our Sun Wakes Up! Soon to be named Region 4294 fires an M5.96-flare at an R2-level radio blackout now! Expect signal degradation on VHF and HF dayside radio bands in the western hemisphere over the next hour, especially western South America, Hawaii & Asian Pacific (colored regions in map).

Bouncing in the blast wave! Check this high detail (denoised) view of a massive filament like a solar skyscraper. A farsided solar storm launch causes this springy structure to bob up and down in the wake of the blast. Taller than 7 Earths, it will launch soon, but towards Saturn, not Earth.

As expected, we are now in a fast solar wind stream from this highly irregularly shaped coronal hole. We are passing through the upper portion of the fast wind pocket, but active Region 4292, could cause highly variable wind. Aurora chasers watch for this bumpy wind. It could trigger substorms!

This coronal hole could give us uneven bursts of fast wind thanks to active Region 4292 which has emerged right in the middle of it. Expect several magnetic polarity inversions in the fast wind stream too, thanks to this subtle complexity!

An equatorial coronal hole is facing Earth. We should expect some high-latitude aurora activity from this on or around 27 Nov.
Some interesting looking prominences are visible on images from the ground-based Solar Flare Telescope at Mitika, Japan.

I've been encouraged to do infographic summaries of my forecasts. Here are 2 different versions. l would like your honest opinions. Which of these do you prefer, straightforward and easy or futuristic and spacey? Here is a link to my recent forecast if you want a deeper dive: youtu.be/FOLDm_N6ft8

Here we go! Region 4274 fires a big X1.8-flare now! HF and VHF radio is getting hammered by an R3-level radio blackout. Expect degraded radio & GPS reception over the next hour on Earth's dayside, especially the Western Hemisphere, Hawaii & West Africa (colored regions in map).

Along with the Sun's farside blasts, several solar storms are headed to Earth! Expect a bumpy ride through October 28. Aurora chasers at high latitudes could see decent shows. HF radio & GPS users expect better reception on the dayside. See my latest forecast for more https://youtu.be/-_pYGbD1l00

Space Weather has picks up in a big way! Region 4246 launches 4 solar storms towards Earth. Region 4248 and 4250 are entering the same hot longitudes and are becoming more active. Expect big flares, HF radio blackouts and & storm launches to continue! Strong Earth-impacts peak October 15-17.

This is just mesmerizing! The way the #aurora undulates looks almost like an undersea creature swimming. Hard to believe it's this bright on an iPhone. Great capture. Thanks for reporting!

Truly an unbelievable night of aurora up in the Yukon Territory. Thanks for all the tips @vincentledvina.bsky.social

If you take long exposures, your cell phone camera might be able to pick up the colors that are too dim for your eyes to see. Thanks for reporting!
Aurora borealis for some tonight at Chicago -- I don't see it but others do with cameras. Bz is below -10 pushing -20 at times

Omg look at this GORGEOUS aurora in Posio, Finland happening right now! Beautiful green and red curtains are filling the sky. Europe is getting absolutely bathed in aurora tonight. Amazing stuff!

One of the best Aurora shows I’ve seen. Legit just stopped and watched it dance. Big camera is shooting. This is just iPhone again.
