Look at the magnitude of that X5.16! Small wonder then that strong showers of Solar particles have been swarming satellites post-flare:

This was the CME that birthed from the X5.16:

And since then until at this time of writing, this is what is showing:

SpaceWeather reports an on-going Ground Level Event:

A 'GROUND LEVEL EVENT' IS UNDERWAY: Yesterday's X5-class solar flare from sunspot 4274 hurled a fusillade of energetic protons toward Earth. Some of the particles are so powerful, they are penetrating the atmosphere all the way to the ground. "This is a very significant event," says Professor Clive Dyer of the Surrey Space Centre. "Neutron monitors around the world are detecting it."  

Please read the article at their site here.

 

I added this afterthought to Part 1:

This makes it five X-class flares since 4 November 2025. I can't help but notice that we've not had any X-class flares for months since 20 June 2025....then our Sun belches out five in a span of 8 days....soon after its rendezvous with 3I/Atlas on Perihelion 29 October 2025.

Yikes. Again. 

This is the on-going Solar storm that was predicted:

Radial Velocity is at the white band, and this is forecast for later, where we're in the black band, about 1400km/s:

The animation below suggests that 3 different CMEs merged together, resulting in the expected situation later today:

https://www.swpc.noaa.gov/products/wsa-enlil-solar-wind-prediction

The first two (red and white) were CMEs hurled out prior to the X5.1 flare, which itself produced the third one (black) that is expected to catch up and join the other two, with all three merging together. They call it a Cannibal CME but I'll just use the term "merge", thanks.

 

It's very choppy out in Space-Sea:

We are in a Plasma Tidal Wave.
 

I'll finish up here and move on to the next post.

Yikes. An X5.16 😯  This just occurred so I can't find much else, but I do hope there will be a video of this flare, it's a strong one ~ the strongest since 31 October 2024 (X2.03). And look at the time-stamp....it's 11-11 at one hour short of 11:00am.

This makes it five X-class flares since 4 November 2025. I can't help but notice that we've not had any X-class flares for months since 20 June 2025....then our Sun belches out five in a span of 8 days....soon after its rendezvous with 3I/Atlas on Perihelion 29 October 2025.

I believe we'll get quite a bit more data on this soon.

3I/Atlas Updates @10 November 2025

Michael Jaeger / SpaceWeather

Amateur Astronomer Michael Jaeger once again steps in to provide decent images of 3I/Atlas when seemingly no high-powered telescope arrays are able to do so. Either that, or available images/data have been withheld from the public.

The above image shows 3I/Atlas as at 8 November 2025, with what looks like....5 tails? Including the anti-tail that is apparently still present. So now, our Visitor has not 1 but several tails....but with a "complex structure". Another anomaly, it would seem.

From SpaceWeather:

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)."

Here's a good one from another amateur Astronomer Alberto Quijano Vodniza:

SpaceWeather

 

We have another photo of our Visitor on 9 November 2025, this time from Frank Niebling and Michael Buechner who are, yep you've guessed it, amateur Astronomers:

SpaceWeather

From SpaceWeather:

"Despite the comet's low altitude (9^o to 12^o) and interference from bright moonlight (82 % illuminated), we were able to capture this image with nice details," says Niebling. "The picture is heavily processed to show the antitail on one side and the 'smoking' tail on the other."

Those abominable lines? SpaceWeather explains:

One more thing: What are all the streaks in Niebling's photo? Starlink satellites. Earth is surrounded by more than 8000 of them, so it is almost impossible to take photos of this low-hanging morning comet without Starlink interference.  

As expected, Avi Loeb has given his analysis, but he rather interestingly refers to those "tails" as "jets", and identified not one but two anti-tails. He also points out that the anti-tails must have properties which are able to overcome our Sun's solar wind speeds, unlike that of a natural Comet.

He additionally makes some other propositions suggesting that 3I/Atlas may be much larger than the officially reported 5km and that "technological thrusters" could be present.  Please read the report here.

X1.21 Flare @10 November 2025

© Laboratory of Solar Astronomy, SRI RAS

We just had another X-class flare, X1.21 this time. That makes this the fourth one in less than a week.

I can't find any resources at this time since it only occurred less than a couple of hours ago, based on the above chart. Once I see something relevant, I will update here. Meanwhile, I think this could be the X-flare:

C/2025 V1 Borisov: Another Tail-less Comet

TheSkyLive

2025 seems to be fast becoming the year for fascinating Comets, or pseudo-Comets. This new kid on the block seemingly popped into view rather suddenly. I don't know details, but I'm wondering how this new Comet got so far into our Solar System before it was discovered. Of course, there could be a very simple Astronomy-based reason of which I'm unaware, but looking at its orbit, it just seems peculiar that this one sneaked in unnoticed until only recently.

There are already many online sensationalist reports exclaiming that C/2025 V1 Borisov is a sort of probe or craft released by 3I/Atlas, supported by the situation that its position was between the latter and Earth when it was discovered. And of course, that it is tail-less.

Anyhoo, I wrestled with the following chart (as best as I could, given my very extremely novice status) to determine the orbital plane of 3I/Atlas, C/2025 V1 Borisov and Earth on 3 November:

....and it does look like all three are sort of on the same plane.

Its discovery was reported by Comets and Asteroids:

Comet C/2025 V1 (Borisov) was discovered by G. Borisov on 2025 -Nov-02.10833 UT at magnitude 12.0 G with coma diameter 25 arcsec, and no tail from L51 MARGO, Nauchnyi using a 0.50-m f/1.9 reflector telescope. The comet is currently in Virgo low in the eastern morning sky. 

 

MPEC 2025-V40 : COMET C/2025 V1 (Borisov) was issued 2025-Nov-05 and reported the discovery announcement, confirmations, observations, orbit, and ephemeris.

Gennady Borisov is the same amateur Astronomer who discovered our second Interstellar visitor 2I/Borisov ~ which had very Comet-like behaviour, tail and all.

Orbital Today carried some interesting details:

A Peculiar Absence Of A Tail

Unlike many comets, C/2025 V1 Borisov appears to lack a prominent tail, which has stirred curiosity and, inevitably, online speculation. Some enthusiasts have linked it to another space traveller, interstellar comet 3I/ATLAS, which has also been the subject of dramatic theories.

Astronomers, however, say there’s no mystery at all. The comet’s subdued appearance is likely due to its composition and distance from the Sun, which means it has not yet developed the glowing tail typical of highly active comets. Scientists confirm that C/2025 V1 Borisov originates within our own Solar System, most likely from the distant Oort Cloud.

Avi Loeb weighed in as well ~ please visit his site to read his article where he indicates an absence of relationship between this new Comet and 3I/Atlas. He also brings up the latest image of 3I/Atlas which shows unusual "jets" emanating from the body. I will get to that in the next post. Fascinating stuff ~ 3I/Atlas continues to present peculiarities.

In the same article, Avi Loeb also includes a link to a recent interview with NewsMax ~ it's brief but had good relevant questions.
