Perihelion Solar Activity & 3I/Atlas Update

SpaceWeatherLive

We have CMEs galore around 3I/Atlas' perhelion on 29 October 2025 ~ here are some examples for each day between 28 October (above) and 31 October 2025:

SpaceWeather has the following update on 3I/Atlas ~ it's ironic that we're getting data about this Visitor from mediums other than the ones who should be updating us. Even previous sightings made available to the public have come from amateur Astronomers instead of "official sites".

RAPID BRIGHTENING OF COMET 3I/ATLAS: Spacecraft monitoring the sun witnessed a dramatic surge in the brightness of Comet 3I/ATLAS as it plunged toward its Oct. 29th perihelion. Qicheng Zhang (Lowell Observatory) and Karl Battams (U.S. Naval Research Laboratory) reported the phenomenon in a preprint submitted to the Astrophysical Journal Letters on Oct. 28th.

"The reason for 3I’s rapid brightening, which far exceeds the brightening rate of most Oort cloud comets, remains unclear," the authors say.

And here are the current positions of the 6+1 Comets/Pseudo-Comet in our Inner Solar System right now (2 November 2025), the new addition being 164P/Christensen:

The positions of the above four Comets now.... 

3I/Atlas isn't shown in the above diagram, but here it is below ~ perihelion is 29 October:

And Comet Wierzchos ~ also not shown in main diagram ~ is quite close to Comet Lemmon:

Our Sun has been spewing massive CMEs continuously for some days now. Here are just some examples, all of the data is taken from SpaceWeatherLive.

26 Oct 2025 ~ what are those black streaks?

25-26 Oct 2025

23-24 Oct 2025

22 Oct 2025

And remember we also had a super-humongous one on 21 October!

Sun-Comets-3I/Atlas interactions happening.
