Re: Comet of the century or pipe dream?
Thanks Rob! All, coming back to the possibility of recovery attempts in the coming decades. I really hope it would be possible withing the next 20 years. And I really wonder... I've read somewhere

Re: Comet of the century or pipe dream?
Hi Maik: very nicely done! To borrow from Woody Allen: "Some people want to achieve immortality through their works or their descendants. I prefer to achieve immortality by not dying." So far, so

Remnants of Comet C/2025 F2 (SWAN)
On the evening of 2025 April 29 Comet C/2025 F2 (SWAN) had a 9' long tail at a position angle of 349 degrees from where the comet coma use to be before the comet disintegrated. On the evening of 2025

Hi Thomas, Nick at all, my last image of the "Perihelium" of the Comet C/2025 F2 SWAN.... Very clear sky, despite moon light and light pollution... 68x7 sec at 1,84 Sec per Pixel with C14 F7,5 and CCD

Re: C/2024 G3 ATLAS orbital plane crossing
Just a follow up on this, I tried a visual observation this morning using 15x70mm binoculars, but estimated fainter than mag 10. Here¡¯s an image of C/2024 G3 ATLAS on 2025 April 30 at 19:30UT. Using

Re: C/2024 G3 ATLAS orbital plane crossing
Nice work Michael! here's my shot from tonight, with 6.4 degrees of tail visible. What a change from a few weeks ago. Cheers - Rob Kaufman

C/2024 G3 ATLAS orbital plane crossing
Hi all FYI. Earth is now crossing the orbital plane of Ghost comet C/2024 G3 ATLAS. This Image was taken on 2025 April 30 at 09:15UT using a remote telescope ITEL-T70 Chile 135 mm f/3.5 Samyang Lens +

Re: Possible detection of C/2025 F2 on April 28.86
Nick, thanks for the photo. I now realise that I also caught the patchy remnants of the comet about 20-30 minutes after your picture. Photo was taken April 29.91 with a Seestar 50 for 4 minutes and

Nick, Andrea, thanks for your update on successful observations, great achievment! It is quite a challenge to image this fuzzy dust cloud and all depends on athmospherical conditions. Despite fairly

Re: Possible detection of C/2025 F2 on April 28.86
Thomas, Thanks. That's a great image. I've be plagued by distant cirrus near the horizon to my northwest (probably aircraft contrails) so my transparency has not been very good. I did have slightly

Re: Comet of the century or pipe dream?
Hello Nico, thanks for your comments and your simulations. Regarding the discrepancies I think all depends on the setting of parameters which of course inhibit certain uncertainties. You'll see that

Re: Comet of the century or pipe dream?
Hi Maik and Gary, That is a fascinating paper, congratulation for the huge work behind this ! I could not resist running simulations of the tails of the comet for the different passages mentioned in

Re: Comet of the century or pipe dream?
A fragment separating from the nucleus at a typical ~1 m/s at perihelion would have a difference in orbital period of +/-6 years. Being an instrinsically bright comet with a presumably large nucleus

Re: Comet of the century or pipe dream?
After reading a comment on Facebook, I'm wondering how likely it is that there could exist smaller fragments of this comet, that would have been unobservable in the 18th century or before, but that
