Sol (Sun) and its phenomena

The other round of electromagnetic perturbations cashed by the Earth on the 8. This is at ground level, GOES is at space level (satellite measurement):

personally I wouldnt label it angry !!

A BIG ANGRY SUNSPOT IS FACING EARTH: This weekend, active sunspot 4274 is directly facing Earth. With an unstable delta-class magnetic field, it poses a threat for powerful X-class solar flares. If such a flare does occur today, it will certainly be geoeffective.


COMET 3I/ATLAS HAS SPROUTED AN UNUSUAL TAIL: After passing behind the sun in late October, interstellar Comet 3I/ATLAS is now visible from Earth again. Astronomers are photographing it in the pre-dawn sky (constellation Virgo).


Michael Jaeger of Austria has been tracking the comet since it re-appeared on Nov. 4th. "We have something unusual to report," he says. "3I/ATLAS showed a complex tail structure early this morning (Nov. 8th)."

Just a little hint

When you refer to spaceweather.com - do not use the main link to the site - because the content always changes / gets updated with whatever is most actual.

So, if you wish to refer to a specific article or event - click on their time machine (upper right corner) with the appropriate date. Then copy the link. That way you preserve the content of a certain date, to everyone who later wishes to read about it - also will access that very article.

Another X-Flare!

A long duration X-Flare (X1.21) was observed around AR 4274 peaking at 09:18 UTC (Nov 10). In fact the solar X-Rays were at the X-Class threshold for over a half an hour. A type II radio emission with an estimated velocity of 1321 km/s was recorded. Coronal dimming is evident with this latest event meaning a CME will be produced. A further update will be provided regarding a possible Earth directed component.

Another X-Flare!

From the Russian institute telegram's channel:

The mass ejection from the new flare will catch up with and absorb the plasma cloud ejected yesterday

The speed of the new plasma ejection, measured near the Sun, appears to be at least 1200 km/s, which is almost twice the speed of yesterday's event at 720 km/s. This means that the gas cloud ejected today will catch up with the plasma ejection from yesterday's X1.79 flare currently spreading through space and they will arrive at Earth together — preliminarily, still at the junction of November 11 and 12, that is, possibly tomorrow evening.

The presence of a frontal plasma ejection has been confirmed visually at this time. Due to its high speed, the gas cloud has moved more than 10 million km away from the Sun in 3 hours and is clearly visible in images from coronagraphs observing the near-solar space. However, there was no doubt about the presence of an ejection toward Earth, and the main interest was precisely its speed, which has now been measured.

At the moment, strictly speaking, despite the very strong flares in recent days, there have been no extreme consequences for Earth so far. Very strong (record-breaking for the year) magnetic storms were expected on November 7, but then the solar hits only grazed Earth. The magnetic storms of G2-G3 level that actually occurred then can be considered a stroke of luck. Yesterday's ejection was also unimpressive, ultimately slow, and moreover, noticeably moved upward above the plane of the planets. In this sense, Earth now has to test its luck for the third time in a row over the next two to three days. Perhaps it will succeed. However, we still need to see what the mathematical models will say in a few hours.

This latest flare also sent the proton flux above warning threshold:

Another X5.16 flare from AR4274:

From spaceweather forum:

"Look at the protons shooting up too, even the >= 500 MeV protons. This flare was incredibly powerful!"

 

[Puma]

AR4274 is now a massive sunspot measuring 1100 MH. AR4276 continues with its beta-gamma magnetic field, and the remaining active regions retain their stable magnetic fields.

​

BANG! The 6th strongest solar flare of the current solar cycle in terms of peak X-Ray flux was just detected around AR 4274 peaking at 10:04 UTC (Nov 11). The event reached X5.1 with a wide area of coronal dimming already evident meaning an energetic Earth directed CME will likely result from this. Stay tuned for the latest updates.

UPDATE: Energetic proton levels are on the rise and a bright CME is now emerging. Although X5.1 ranks 6th on the brightness scale, this event could be the most energetic of the current cycle.

With this energetic event, people may experience: ringing in the ears, restless sleep, pressure headaches, sudden fatigue, bursts of energy, or a feeling of "disconnecting" for no apparent reason.

Will we see a major seismic event in the coming days? A powerful volcanic eruption? Social unrest?

We're going to get spanked in the next few days. With this latest X5.1 CME, I would not be surprised to see an upgrade to a G4 SEVERE geomagnetic storm.​

The incoming CME will likely prolong an already expected geomagnetic storm and could push it to the Severe (G4) threshold in the days ahead. A further update will be provided once a tracking model and forecast is released. SolarHam.com

A crowded space

 

[Laurentien2]

Here is the latest from Stefan Burns about the geomagnetic storm that is about to hit the earth. A 1-2-3 punch that may get as high as a level 5 geomagnetic storm. So for those lucky enough to have a clear night, aurora may be view quiet far south.
About object C/2025 V1 Borisov, he said yesterday that it as disintegrated.

Solar activity for the past 72 hours has been a 1.7 X-flare, 1.2 X-flare, and new 5.1 X-flare, all of them launched powerful coronal mass ejections (CMEs) towards Earth. G2-G4 geomagnetic storm conditions are to be expected in less than 24 hours, and that could spike to G4-G5 conditions shortly afterwards late November 12th early November 13th.

We now have the record for the current 25th solar cycle:

Лаборатория солнечной астрономии (XRAS)

Математическая модель предсказывает на завтра самый сильный удар по Земле в текущем солнечном цикле К результатам моделирования сложно что-то добавить. Все утренние рассуждения о приходе к Земле двух выбросов от вспышек X уровня, казавшиеся такими значимыми и важными, утратили актуальность. Все...

t.me

All the morning arguments about the arrival of two emissions from level X flares to the Earth, which seemed so significant and important, have lost their relevance. All the plasma clouds that are currently flying towards the planet will catch up and absorb the emission from today's flare. The impact on Earth is expected tomorrow, and according to the model, it will be the strongest in the current 25th solar cycle.

The graph shows the early geomagnetic forecast (soft branch). The main one is still being calculated. It doesn't make any deep sense to anyone, and it's almost certain that when the actual schedule is applied to this forecast tomorrow, there will be nothing in common between them.

Лаборатория солнечной астрономии (XRAS)

Сформирован ранний геомагнитный прогноз На графике — ранний геомагнитный прогноз (мягкая ветвь). Подсчет основного пока идет. Никого глубокого смысла он не имеет, и, почти наверняка, когда завтра на этот прогноз будет наложен фактический график, между ними не будет ничего общего. Честно...

Honestly, no model in the world knows how to calculate such events. We do not know by what criteria NOAA, which makes such final decisions, chose this particular branch from the tree of options. Most likely, they just tossed a coin.

Reassuring!
