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

Great image! Unforgettable Comet! Regard [email protected]> ha scritto:

Wow, very nice images Michael and Rob of the 3+ month disintegrated comet. Cheers, Erik

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

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 +

Hello, a recent photo of the remnants of comet C/2025 F2 (SWAN) taken by BBO on 2025.04.29 https://www.danilopivato.com/solar_system/comets/c2025_f2_swan/c2025_f2_swan.html Best, BBO

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

Dear all, from Schiaparelli Observatory the ex comet C2025 F2 near the NW Horizon two days ago in excellent sky condition Best Regards Andrea Aletti e Federico Bellini MPC204 [email protected]>

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

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

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

Two nights earlier I have had a chance to observe whats left of the comet from Weimar, Germany. The comet was at an altitude of only 5.5° above horizon but I gave it a try with my RASA 11" and

Possible detection of C/2025 F2 (SWAN) on April 28.86: https://britastro.org/observations/observation.php?id=20250429_063941_2990db2ceeed4e3a A very noisy image taken in very bright twilight but there

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

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

Qicheng, This is the 2097 orbit, "linked" to 1402 with a fixed perihelion date for 1402 which gave the best agreement with the other apparitions. Orbital elements: C/1743 X1 Perihelion 2097 Dec

Finbarr, hmm, you are right. The dates were later added by the editors, prior the final proof. I did not check these. Maik -- "One cannot discover comets lying in bed." * Lewis Swift

Very interesting! Do you know what the uncertainty on its angular elements looks like? For multi-apparition objects observed only near perihelion, the positional uncertainty is generally dominated by

Very interesting indeed. One quick note re William Edward Plummer; his dates are 1849-1928. Finbarr.
