Here's the last frame in the sequence, minus the mp4/streaming compression. Still a tad over-exposed in my processing, but certainly much better than the default processing we see on the SOHO site.

As many have pointed out, the LASCO images on the SOHO website are saturated. So this is the result of my own algo for processing them.

And I will echo my sentiments from yesterday: This. Comet. Is. RIDICULOUS! 🤩😍 ☄️🔭☀️

I really, REALLY can't get over just how beautiful this comet is in our LASCO images! I mean, I've seen more than a handful of comets in this data over the years (~5,200 to be exact - not that I'm counting...) But I've really gotta say... this might be the pick o' the bunch right here. WOW 😱😍☄️☀️🔭

Short animation of C/2024 G3 (ATLAS) in the Blue filter on our ESA/NASA SOHO/LASCO C3 camera. ☀️🔭 Seeing lots of beautiful striations in the tail! 😍

Zoomed in. No processing at all

Comet G3 ATLAS looking great in the raw Blue filter LASCO C3 images! ☀️🔭

G3 ATLAS is now entering LASCO C3! ☀️🔭🛰️ Judging by the saturation spikes, it's at the upper end of our brightness estimates (maybe mag -1 or so? Just eyeballing, so could be off on that). Anyway, follow along over the next few days: soho.nascom.nasa.gov/data/realtim...

Transits through the SOHO LASCO C2 and C3 fields of view in 2025 are now posted: sungrazer.nrl.navy.mil/transits_2025

Huge thanks as always to Sungrazer Project contributor (superstar!) Worachate Boonplod for compiling the list/graphic.

Of note: C/2024 G3 (ATLAS) enters LASCO C3 on Jan 11! ☀️🔭☄️

Antares and M4 are center-stage in SOHO/LASCO C3 today. Milky Way turns up later this month ☀️🔭

Eleven years ago today 😳 Comet ISON certainly captured the attention of a global audience! Sadly it didn't survive, but the memories live on! ☄️☀️🔭

Should be entering the LASCO C2 field of view very soon.

And no, there's still absolutely no hope it'll survive past the Sun. It will already be an extended (and furiously sublimating) rubble pile. Nice while it lasted tho! ☄️☀️🔭

And zoomed in on the comet ☄️

Aside: I can never find a good mp4 setting that gives good results for posting LASCO image sequences. This drove me nuts on Twitter, and it's the same here. It's all down to how they compress the data for streaming. If anyone has any recommendations...?

Here's the data we have so far showing the new (soon-to-be-vaporized) sungrazing comet in our LASCO C3 field of view. Lots of beautiful CME's kicking off too! 😍

See for yourself at the SOHO movie theater: soho.nascom.nasa.gov/data/Theater/

The new sungrazer continues to perk up! Lots of solar activity overnight too, and we seem to have a moderate particle storm in the images (all the white "snow"). These are relativistic (i.e. near speed of light) particles blasted out by solar flares/CMEs*, that reach the spacecraft within ~minutes

Something to 👀. New sungrazing comet in ESA/NASA SOHO/LASCO C3, found last night by citizen scientist Zesheng Yang. It should get pretty bright -- maybe Vmag 5 or so? Right now it's hard to spot, but I promise it'll be easy to see by tomorrow. ☄️☀️ Follow along: soho.nascom.nasa.gov/data/realtim...

Hey there! 👋 For those that don't know me from the Other Place, I'm a scientist involved in heliophysics space missions, but with an emphasis on observations of comets & asteroids from those missions. So I Tweet...🤔 ...Bleet? 🤷... mostly stuff like this👇 (Comet McNaught in 2007, NASA STEREO-A)
