A month ago, I had written (here):
We've not been getting much Earth-facing strong Solar activity for some time now but as per my earlier post, our Sun is still very active in other parts of the Solar System. I feel that 3I/Atlas will have some effect on our Sun as it approaches nearer in the days to come.
With its estimated size (still under debate with Scientists but generally agree that it's "large"), imagine the amount of Cosmic Plasma and its inherent "data" that 3I/Atlas is carrying. There's some serious upgrading happening here.
I was expecting 3I/Atlas to affect our Sun but instead it's the other way around!
SpaceWeather reported on 23 September 2025 (here) that a forecast showed 3I/Atlas flying straight into a CME around 24th or 25th of September 2025:
Of course the Visitor isn't shown on the forecast ~ but I'm assuming the deduction made is that the CME is heading Mars' way and that's the time that 3I/Atlas would be approaching Mars as well, as shown below:

I can only imagine what effects that would produce! SpaceWeather highlighted some relevant considerations in this excerpt:
A CME IS HEADING FOR INTERSTELLAR COMET ATLAS: How often does a CME from our sun strike a comet from interstellar space? Almost never--so tomorrow’s collision is worth watching. According to a NASA forecast model, a CME launched on Sept. 19th will reach Comet 3I/ATLAS on Sept. 24th or 25th. CMEs hitting Solar System comets have been known to kink or even disconnect their tails. What happens to an interstellar comet is anyone’s guess.
Are we getting flooded with even more Cosmic Plasma from this noteworthy encounter?
And if this isn't exciting enough, we have Comet Swan and C/2025 K1(Atlas) both in the vicinity of Mars right now as well. Did they also get impacted by the same CME?

I can't be certain, but the main image at the top of this post could be the CME in question. It blasted out on 19 September 2025.
During the time period of 24 - 26 September 2025, we had some SR whites:
