Dear Krisztian, Med, all, It’s still quite early in the game, but, indeed, this object does look interesting. There does seem to be some similarity to the orbit of the Daylight Comet of 1910,

Hello all , I know it's still too early to ask this, as the data is still uncertain, and I might be overstepping into something I don't fully understand, but I just realized that this object shares

Hi Folks, What do you think about NEOCP object A11nyuL, which is a possible small perihelion distance comet? Thanks, Krisztián

Hi All. Just for information - the recent moderately bright periodic comet 217P/LINEAR is visible in images taken by UV camera SWAN since May 2, 2025. X-Y for 22/05 (0,0 - upper left): 527-301 at

Hi All, I have just updated my analysis of the currently brighter comets. You can find it at the URL http://fg-kometen.vdsastro.de/aktause.htm Kind regards Andreas Kammerer

Hello all, I managed to capture the remains of disintegrated comet C/2025 F2 SWAN. Attached image was taken on 2025 May 16 at 23:00UT using a remote telescope in Chile, ASAN250 f/3.8 + ASI6200mm

Following the most recent outburst the coma is developing as the comet fades. [image: image.png] Regards, Wayne [email protected]> wrote:

Hello Taras and the group, My observation of 29P with my eQuinox2 (smart telescop UNISTELLAR, Newton 115*450, data with Tycho Tracker) last night in France with magnitude m2 equal to 14.3. Image

Hi all, Comet 29P/Schwassmann-Wachmann is most likely in a strong outburst. I imaged this comet earlier today and noticed a condensed inner coma of 0.4' in diameter with classic outburst appearance.

Hi Manos, Thanks. Yes, I hope that it will be recorded and made available online after the meeting. Nick.

Hello, thanks for informing us. Very nice program with interesting talks! Unfortunately too far from me in Athens :) I am so impressed that will be held in a church! Wish you all have nice time in the

The British Astronomical Association will be holding a joint meeting of its Comet and Meteor sections in Edinburgh on Saturday, 4th October, 2025. You can find a list of topics and speakers at the

Dear Maik, all, I concur that, given the circumstances, it was appropriate to stop the investigation at that point. Indeed, the discrepancy between the Chinese and Roman reports of the 44 B.C. is

Alan, David, I am currently on travel, so please forgive me this short answer. First, please bear in mind that the projected perihelion dates are already quite uncertain in 336 and even more in -43.

Hi David, all, Interesting thoughts. When I was researching this object some years ago I came across the opposite speculation, i.e., it was the Roman dates that are incorrect. (I honestly don’t

Hi Maik and all, I have been thinking about the Great Comet of -43 and the possibility that it was a return of the 1744 comet.? If you are correct about the orbit of this latter object (and you

Quicheng,

I'm crudely estimating from the posted uncertainties that the 3σ uncertainty ellipse is somewhere around 20 arcmin across, which is rather large for JWST whose largest camera only covers a pair of

Mag 34 for JWST is ultra-deep field like when Hubble reaches mag 31+. I'm not convinced that they would make such an ultra-deep field just to recover such a comet that would anyway be recovered long

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
