A coronal mass ejection left the sun on the 6th following an M class solar flare and a filament eruption, and resulted in a full-halo, earth-directed components likely. Most model had the estimated time arrival for today (Monday, 8th) but that did not occur.
Space weather🤷‍♂️

Here’s STEREO-A view of the CME (both HI2 and HI1) as of the a few hours ago. Maybe an ETA between that of NOAA’s model and ELEvo?

I am getting Jan 19th vibes, and i’m cautiously optimistic (i wasn’t for the CMEs from the other day)

Noctilucent clouds season kicked off with a bang, as their visibility reached as far south as Austria 🇦🇹, this morning. This is from Panomax webcam of Raxalpe, but someone was able to photograph them nearby. Keep an eye open for tonight and monitor MAARSY radar.

@MesoCellWx @TamithaSkov @Vincent_Ledvina @WickyDubs2 sorry, i’m tired and and thought it was a timelapse you created! thank you for the source link

WOW, Alessandro Brambilla (from Italy) caught the pink emission from falcon 9 even better! https://t.co/EoutKwRMOp provides an excellent explanation.

HERE IT IS, falcon 9 second stage from northern italy!
Thank you @XploraSpace

Day 25 of lf posting until a new kreutz comet is discovered, hopefully it won’t be long. This video here shows kreutz comet C/024 S1 that disintegrated in late october 2024 a few days after C/2023 A3’s show. The view is from CCOR-1 background-substracted imagery.

Day 22 of posting until a new kreutz comet is discovered, hopefully it won’t be long. Here’s mirrored video of C/2025 R3 to resemble C/2023 A3’s path in CCOR-1. Truly a MASSIVE difference, panSTARRS is nice but tsuchinshan was on another level and a comparison is not fair

[Spaceweatherobserver @SpaceweatherOB]

@TamithaSkov “yesterday on HF, D-layer absorption was unusually higher than expected. The 40m band was practically closed despite the heavy flares were 2 days ago. Is there still stuff in transit or other activity keeping the ionosphere unsettled?”

[fra @frapepppemaria]

Bye bye comet C/2025 R3, it was nice following your journey across CCOR-1!
The comet has now left CCOR-1 FOV and will soon leave LASCO’s too. Although it was still a nice sight, had it been more dusty, we would have witnessed an even greater show, that’s for sure. Thank y’all🙏

[fra @frapepppemaria]

COMET C/2025 R3 UPDATE:

It is halfway through CCOR-1 and LASCO’s FOV and it will be exiting tomorrow. As expected, forward scattering enhancement has been limited by the lack of substantial dust release.
It will probably be back at mag 4 by the time it’s visible again in the SH

[fra @frapepppemaria]

WHAT A NICE SIGHT OF C/2025 R3!

The comet has also entered CCOR-1 (background substracted) imagery* which i particularly like and it looks quite nice! If this comet weren’t so dust poor the view would be even better…
*LASCO takes a while to update and is not as constant anymore

[fra @frapepppemaria]

HERE IT IS, COMET C/2025 R3 HAS ENTERED LASCO C3 FOV AS EXPECTED. It looks decently bright, waiting for more imagery to be updated later this evening.

[fra @frapepppemaria]

COMET C/2025 R3 ENTERED STEREO-A HI2 FOV

On the 18th comet C/2025 made its appearance in HI2 imagery showing nice tail structure and tail disconnection events, beautiful sight! I’ll try to post a GIF as soon as i have some time to download all the frames.

Day 9 of posting until a new kreutz comet is discovered, hopefully it won’t be long. not comet related, but a satellite (possibly a stage from a chinese mission) reentry was observed earlier today (3:44 UTC), as this video from southern Italy shows.

[fra @frapepppemaria]

Btw a new kreutz fragment was visible in CCOR-1 imagery yesterday (April 11th) and has likely already disintegrated, but maybe it made it into LASCO C2 FOV. This one was fainter than the previous but still relatively bright and a nice sight.

[fra @frapepppemaria]

Day 8 of posting until a new kreutz comet is discovered, hopefully it won’t be long. This is comet C/2025 R3. Vivid green that makes it obvious to spot it in the frames. I’ve looked through many webcams, but this is by far one of the best view (clouds limit the others a lot).
