Wonder if it is some sign of the help that is on our way.

Crikey I bloody hope so.

That was comet 3I/Atlas discharging the solar capacitor:

Выброшенное облако плазмы через 2 суток ударит по объекту 3I/ATLAS Согласно оценкам, облако плазмы, выброшенное после сегодняшнего взрыва, направлено точно (в пределах 10-20 градусов) в направлении объекта 3I/ATLAS, который проходит сейчас с противоположной стороны от Солнца на расстоянии около...

The ejected plasma cloud will hit the 3I/ATLAS object in 2 days. It is estimated that the plasma cloud ejected after today's explosion is directed precisely (within 10-20 degrees) in the direction of the 3I/ATLAS object, which is currently passing from the opposite side of the Sun at a distance of about 200 million km with a slight shift towards the northwest. It was in this direction that the ejection went. The ejection front will hit the facility at about 3 p.m. Moscow time on Friday, October 24. The comet will stay inside the plasma cloud for at least 1.5-2 days. In general, let's see how the aliens are with weather sensitivity. In H. G. Wells' War of the Worlds, nature had enough of the usual flu viruses.

This last sentence is the Russians mocking the disinfo campaign about 3I/Atlas being an alien spaceship.

Blasting Atlas again...

More coronal mass ejections to report, all of which appear to again be farsided. The first CME well behind the northwest limb likely originated from the same sunspot region that produced the massive halo CME observed on Tuesday. The second and fainter CME heading to the south was the result of a prominence eruption beyond the southern limb of the Sun that was observed in GOES SUVI imagery this evening. SolarHam.com

AURORAS SURROUND COMET LEMMON--AGAIN: Comet Lemmon's close approach to Earth on Oct. 21st coincided with the onset of autumnal aurora season. The resulting photo-ops have been superb. Here's the comet surrounded by red oxygen auroras over Germany, and purple nitrogen auroras over Alaska.

Yesterday's emission on the model. Who knows how many X-points it was. To be honest, it's scary to even estimate. It looks very similar to X10.

About the power of yesterday's flare

In response to questions asked, below are some explanations about the power of the event that occurred.

Reliable estimates of the power of yesterday's solar flare are impossible, but there is a possibility that the event is the largest or one of the two largest in the current cycle and falls within the range of X10 - X15. Unfortunately, there is no clear connection between the strength of the plasma ejection and the energy of the flare event. This is because, in addition to the energy of the explosion itself, the Sun's magnetic field also contributes to the acceleration of matter. However, it can also slow down the movement of the plasma cloud. Objective information can only be obtained from direct observations of the explosion site, but in this case, this is impossible. The only spacecraft that could have provided such data, Solar Orbiter, was at a different angle at that moment, from which the explosion area could not be observed.

The closest analogue to the current event is the flare of July 23, 2024 (just over a year ago), with a very similar emission, which also occurred on the far side of the Sun, but could be observed by Solar Orbiter. The latter's X-ray photometers determined a score of X14 for that event. In this case, as already mentioned, it was not possible to obtain such estimates, but visually the events are very similar.

The largest event of the 25th cycle included in the official catalogues is the X9.0 flare on October 3, 2024. In second place is the X8.7 flare on May 14, 2024. In third place is the X7.1 event on October 1, 2024. All events occurred on the side facing Earth. Events on the invisible side are not included in the catalogs.

The resistance in mainstream circles to make even the faintest of connections between 3I/Atlas and the solar flare is mind-boggling. Their modus operandi is to keep us in the dark.

The resistance in mainstream circles to make even the faintest of connections between 3I/Atlas and the solar flare is mind-boggling. Their modus operandi is to keep us in the dark.

Well, it is not much of a surprise if we consider that most of them are also mostly in the dark.

Two predominant models of interest to the situation here are comets as dirty snowballs and Newton's/Einstein's mechanics/gravity that govern the motions in space. Seeing a comet being plasma blasted in relation to one out of cca hundred X-class solar flares that have been observed over the last few years is statistically more or less insignificant event. So already pre-formed 'conclusion' that solar flaring comes solely from things happening on the Sun has not been actually challenged. Adding to the mix that not every comet in close fly-by to the Sun, which is a rather rare event by itself, triggers strong or any solar flares at all, which otherwise might give a pause to at least some of the scientists, we come to see that there are only a few occasional faint rays of light penetrating the dark domes where they reside in most of their days.

Edit:

That was comet 3I/Atlas discharging the solar capacitor:

In the context described above, this statement, provided without reliable evidence, to the mainstream circles is more or less equivalent to comet Atlas being alien starship.

I can't wait to see what happens at the perihelion (1.36 AU from the sun) of comet 3i Atlas on October 29-30​

The farside of the Sun is where all the action is taking place. Yet another CME is now emerging following an eruption between 17 and 18:00 UTC (Oct 23). Coronagraph imagery over the past three days observed a number of explosions leaving the farside of the Sun, including a major full halo event on October 21st. See comments for a quick video.

I can't wait to see what happens at the perihelion (1.36 AU from the sun) of comet 3i Atlas on October 29-30

The channel of the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences, discard the influence of Comet 31/Atlas on the sun. Not surprised, as the implication could deal a blow to many belief and the world isn't ready for that .. yet. On the other hand, would it fragment after the plasma collision? We won't know until early next month.

Comet Atlas has keeps us in suspense.

Object 3I/ATLAS may be partially destroyed today by a solar plasma impact

Today, in the second half of the day, according to calculations, the interstellar object 3I/ATLAS is expected to withstand an impact from one of the largest plasma clouds in the 25th solar cycle, ejected by the Sun in the direction of the comet on the night of October 21 to 22. There is a high probability that this will be the first such test in the life of the celestial body with not fully understood consequences.

Unlike the inner comets of the solar system, which orbit the Sun and approach it multiple times during their lifetime, 3I/ATLAS is not bound to any star and moves freely within the Galaxy. Considering the low density of stars, a close approach to any of them at a negligible galactic scale distance of 200 million km (about 10 light minutes) is an extremely rare event and may never have occurred during the object's existence. Furthermore, flare activity is characteristic not of all stars, but only of certain types, including our Sun. Finally, the very fact of an exceptionally large plasma ejection at the moment of the star wanderer's closest approach to a randomly encountered star is a rather unlikely event. For all these reasons, it is very possible that the object will today be subjected for the first time in its life to such an impact, followed by being inside a dense plasma cloud for 1-2 days.

The question of the impact's consequences is unclear. Plasma ejections often tear off comet tails but leave their rocky nuclei intact. At the same time, having a rocky nucleus is not mandatory for a comet, as some may be loose snowballs or even just a gravity-bound clump of sand and dust. It is possible that comets of this type orbiting the Sun simply have not survived in significant mass to the present day, and the preserved "strong" comets are exceptions to the rule. What exactly the nucleus of 3I/ATLAS, hidden inside the gas-dust cloud, is remains strictly speaking unclear. Its size is estimated by some to be less than 1 km, and it is impossible to see it in principle. Spectroscopic methods allow some conclusions about the comet's chemical composition but provide almost no information about the physical state of the nucleus.

t can be noted that, in some scenarios, the solar plasma impact may, on the contrary, stimulate an increase in the body's brightness due to an impulsive increase in the rate of volatile substances escaping from the comet's central regions. It is possible that the object will ultimately appear in LASCO images, where it is currently hidden.

Of course, for those who believe that an alien space probe is hidden inside the gas-dust cloud, these considerations will seem meaningless. In this scenario, the main question is whether the ship's creators anticipated the possibility of it being hit directly by stellar flares and whether the probe's radiation shielding will withstand the exceptional power of the event and the fact of a direct frontal impact.

Observing the comet's passage through the cloud or even simply learning the object's condition in the coming days after the impact will be impossible. As already noted, the body is currently fundamentally inaccessible for observation from Earth.

AR4246 appeared on the solar disk in early October and between the 13th and 17th registered an unstable beta-gamma-delta magnetic field capable of producing X-class flares; however, during this period it only produced several M-class flares. Its maximum solar flare was M4.8 on October 15.
​

The daily parade of coronal mass ejections continues. We have two ejections visible so far today and in both cases appear to be related to farsided activity. For those wondering, the source of the large farsided CME on October 21, AR 4246, is still about 6 days from turning back into view. Imagery from STEREO Ahead confirms that the solar flare was likely a strong X-Flare. SolarHam.com​

 

[Puma]

Earth facing solar activity continues at low levels with only minor C-Flares detected. All visible sunspot regions are magnetically stable and there is currently only a 5% chance for an isolated M-Flare today.

The farside of the Sun on the other hand continues to show higher activity. An eruption became visible today (Oct 27) beginning around 08:00 UTC and the associated CME will obviously be directed away from Earth. The likely source of a number of farsided eruptions the past several days, AR 4246, is now around 5 or so days away from returning back into view. SolarHam.com

Solar wind flowing from this southern coronal hole could graze Earth on Oct.29-31

NASA/SDO

Here come the coronal holes! The effects of the high-speed stream from the southern, positive-polarity coronal hole should be affecting Earth soon, probably ramping up today and tonight. Effects could last over several days. G1-G2 storming is possible.

Folks above the 45th parallel should be on high alert this week as mid-latitude auroral displays are certainly possible due to the CIR+HSS this week. The positive polarity favors the current season due to the Russell-McPherron effect, and we should see more negative Bz than usual from this coronal hole. Vincent Ledvina

The perihelion of comet 3i/Atlas is expected to occur at 11:47 UTC (± 1 minute). In a few minutes.

Coronal mass ejections continue.

A bright, asymmetric halo coronal mass ejection (CME) is now visible in the latest coronagraph imagery courtesy of GOES-19. This is the source of a type II radio emission with an estimated velocity of 1279 km/s at 00:10 UTC (Oct 29). Although not for certain, there is the possibility that the culprit was again a solar flare event around AR 4246, now around 4 days away from reaching the east limb. SolarHam.com

Violent explosions continue on the far side of the Sun.

Лаборатория солнечной астрономии (XRAS)

На обратной стороне Солнца продолжаются сильные взрывы. Уже ближе к Земле Новый крупный взрыв зарегистрирован сегодня ночью на обратной стороне Солнца. Мощная активность на невидимой солнечной стороне наблюдается уже около 10 дней, после того, как туда с обращенной к Земле стороны перешла...

t.me

A new large explosion was registered tonight on the far side of the Sun. Powerful activity has been observed on the invisible solar side for about 10 days, after a large group of spots with the number 4246 moved there from the Earth-facing side (Лаборатория солнечной астрономии (XRAS) ). Apparently, during this time, several outbreaks of the highest X score occurred in this center, and for one of them, which occurred on October 22, there are power estimates reaching X10. Although the region itself is not visible from Earth for obvious reasons, the material ejected during the explosions spreads far beyond the solar disk and is observed by telescopes and coronographs.

Anyone know how this could be translated -may well be quite insightful? I couldnt find anywhere on the web pertaining to a translation of this chinese manuscript !​

​

Tian yuan yu li Xuan ji jing zhu zhan zheng ji​

Tian yuan yu li Xuan ji jing zhu zhan zheng ji (天元玉曆璇璣經諸占正集) translates to A Compilation of Divinations from the Tianyuan Jade Calendar and the Big Dipper Scripture. This Ming dynasty manuscript, compiled by Zhan Bin, contains a series of divinations based on celestial phenomena such as the sky, sun, moon, stars (including the Big Dipper), planets, weather patterns, and atmospheric events. These divinations were used for prognosticating events and guiding military and imperial decisions, written in fu verse and illustrated with color plates. The work is preserved in a rare eight-juan, six-volume format and is available as a digital facsimile through the Library of Congress.

edit -apologies for bold type !

There's a study by Arlt and Vaquero on historical sunspots reported in the literature before the telescope was invented. Presumably, they're still going through databases to at least give an idea of the sun's activity throughout known history. Here are some images and excerpts from the study:






This one is particularly interesting, depicting how bizarre was the Maunder Minimum:
