  1. This reminds me of other astrophysical effects. Pulsars have phenomena where some electrons and positrons confined by magnetic fields at lower latitudes flow out one side via the current sheet and eventually return back to the pulsar. That flow, aside from the gamma ray emissions that escape to space, return back and strike the pulsar. I believe this is both inside and outside the light cylinder. This is the generation mechanism of pulsar wind that leads to nebulae around pulsars such as Vela. ill have to locate the paper when I get home, it’s also a lecture on YouTube at Cornell IIRC.
  2. I believe there may have been a stealth CME last night. Looks like it’s relaxed again, most of the active regions shifted to coronal holes. Very weird.
  3. Looks like she got 24 pretty close. Maybe she made some theoretical updates over the years and never updated the old 23 data?
  4. Ahh yes that’s definitely it. It was quite large in size, at least 4 🌎. I find the polar regions of the sun very interesting, been wondering if there’s some vortex structure like Saturn (amongst some other issues). Too bad we won’t find out until the ESA/NASA Solar Orbiter arrives at the higher latitudes in 2026. After the dynamics that showed up at Jupiter’s poles when the first Juno pics started flowing back, I think anything could be possible. I wonder if we will still be in solar minimum then? 😎
  5. Does the flux rise dramatically at the end of minimum or is it gradual? There are a few small active regions but nothing to write home about. I assume this is breaking all current models?
  6. Perhaps it is the translation? The original content was in Japanese. Thanks for the input, but I’m just a joker killing time. Not a professional researcher like you guys. I figure other stars would be a good starting place - particularly solar mass stars if you’ve got them. If you look at red dwarfs like Trappist or Proxima Centauri with lots of tidally locked planets, they produce flares the likes of which humanity has never seen. There was a recent Proxima flare where it was actually brighter than Alpha Centauri for a few hours. Current hypothesis places this cause to be the lack of a radiative zone, but given how many large planets these small stars have in close orbits, I’d be willing to wager there is a clocking effect as well. Trappist is an example of crazy size planets relative to star mass; 8 roughly earth mass planets all hugging the star within 1 AU. Those insane stats could explain monstrous superflares from these dwarf stars. speaking of spots, this coronal hole and the high latitude phages(I think that is correct terminology) is very interesting. It’s nearly reached the South Pole where it looks like it might connect up to that other phage. It’s clear that the magnetic field is increasingly stressed. The brightened area just below the coronal hole is very bizarre, reminds me of Antares 🧐
  7. The asymmetry is very interesting, there must be a cause. Thanks for posting, another rabbit hole to go down! 🤓 Here is an interesting lead of sorts; there is a planet about the size of Jupiter hugging a young 1 solar mass star from about 3 AU. You can see that the star is magnetically stressed where the planet is. https://phys.org/news/2016-06-newborn-giant-planet-grazes-star.amp
  8. Article here, I found it interesting given the hypothetical planetary clocking debate. There is a paper but it is behind a paywall 😒 https://www.phys.org/news/2019-09-plasma-sun-surface-sunspots-solar.html
  9. Thanks for the response. I’ve read that Nature paper and some of the comments being posted on academic sites. Sadly, the situation has devolved into in-fighting about global warming and the discussion about minimum has disappeared. I keep up on direct imaging of other stars, and recall reading in the paper about Zeta Re that not only was Doppler imaging used but also interferometry, so they were able to discern that there was increased levels of magnetism where the dark spots were.
  10. So the flux is down to 66 and the sun visually appears somewhat relaxed again. I wonder if other stars are this dynamic.
  11. Good to go. https://twitter.com/CovertGoat/status/1174405818483011584?s=20
  12. Thanks for the info. Here is the video: https://youtu.be/BdTTSylIHYQ
  13. Can’t get a more serious website because on phone, but do those spots seem to coincide with Jupiter and Saturn being at the exact opposite side of the Sun? Could flux ropes from Jupiter and Saturn “crossing” cause such phenomena? I mention this because I recall seeing a video by NASA of the most recent X class flare sending gamma rays out into space and the Fermi telescope seeing them hit the opposite side of the sun some time later. It was mentioned they traveled along magnetic field lines. While not the same phenomena, perhaps there is a “short circuit” of sorts taking place here between interacting flux roles.
  14. Responding with the first section regarding the magnetic field and will finish the other part at lunch later. Here is a PowerPoint slide from a nasa presentation on the sun and the “11 year cycle” and the field twisting itself up, thereby creating sunspots. The last time I mentioned the “sun” and “birkeland” in the same sentence I got insulted and roasted out, it was on reddit of course. I’ll check that stuff out, thanks. I’ve been pondering if there could perhaps be some “resistance” effect played by the planets on the current sheath.
  15. This is very interesting. I know this is a hypothetical issue, but would sunspots in general still be caused by the field lines being twisted up as is believed now? Or would that not apply any longer? And if so, would that mean that some stars might not even have sunspots? I ask because some stars are very peculiar, they have sunspots in locations that our sun does not. There is a star which has spots at the pole that is visible to us, obviously not sure if they are on the pole facing away. Then there are stars like this monster linked below, which has spots at the equator AND the poles. If clocking applies, do you think other star partners could influence it? Because Zeta Andromedae has a star with inclination at the north polar region which could be causing that sunspot. It also has two partners which are respectively near the equator. https://cosmosmagazine.com/space/starspots-seen-zeta-andromedae
