4. Summary of the discovery

I have completed a nova hunting session, which is my major target of searching, and I still had an extra time. Then, I conducted a comet hunting session in the northeastern sky, and I was lucky enough to shoot a green glowing comet. I checked the position and I wondered if it was an outburst of 8P Tuttle. However, I found the position was different from that of 8P by some 2°, and reported as it a possible new comet.

5. Discovery course

I concentrated on the visual searching of comet until around 2000, and was able to meet a new comet (2). After that I have come to interest in a nova hunting, and I kept searching spending 90% of my activity for nova hunting and 10% for comet.

It was cloudy at dusk on the day before the discovery, and could not take photos for nova hunting in the Milky Way Galaxy. So, on the day I got up at 1:30a.m. local time and headed for the tea plantation where a quarter-hour of drive from my residence. Most part of the summer Milky Way was in the western sky, and I started shooting the Milky Way at 2:08a.m. up to around the constellation of Cassiopeia.

As there was enough time until the start of the twilight, I began to take photos to search for a comet from the southeastern sky, and put the northeast on the backburner where I photographed the day before at predawn.

At the low altitude the sky grew brighter when the shooting area got close to the northeastern sky, and I hurried to take photos with shorter exposure time. Eventually, I finished the hunting session at 4a.m. leaving some planned area to be searched.

I got home and tried to detect objects that are not in the past images using my PC, among which I checked if there was any new object. I noticed a non-stellar object seemingly having some apparent diameter just before the end of the checking work. I thought that I identified a known comet again, and I confirmed using MP checker but no comet was detected.

To make sure what it was I adjusted the brightness of the image using Photoshop Elements and the green star appeared that is typical for a comet.

I emailed Syuichi Nakano, an Associate of the Central Bureau for Astronomical Telegrams and the Minor Planet Center, in Sumoto, Japan, that reported the object is a new comet without doubt. I calmed down and I confirmed if there were any known comets around the position. I found that 8P Tuttle being brightening was near the possible new comet. Immediately, I told Nakano the fact and he said the predicted position of 8P was different from that of the object of interest by some 2°. I remeasured the position of the possible new comet.

Nakano reported the position to IAU and the new comet had been confirmed.

I think back to the situation with a cool head, and I found I was pretty lucky. If I had taken the photo a little bit earlier, the comet would not have been photographed due to the low altitude from the horizon, i.e., the unadjusted image looked like an overexposure photo taken in the daytime. Conversely, if I had shotten a little later, it would have been disappeared in the twilight.

Note of translator

(1) The beginning of the twilight on the day was 3:09a.m. JST (local time). That meant Nishimura took the photo 38 minutes after the start of the twilight.

(2) Nishimura discovered his first comet in 1994: C/1994 N1 Nakamura-Nishimura-Machholz.

Eric W. Elst (1936 - 2022)

Eric W. Elst

Eric W. Elst,

From the MPML (Minor Planet Mailing List)

Eric W. Elst (1936 - 2022) started working at the Royal Observatory of Belgium in 1968 en was active until 2001 (pension). First he did photometry, but around 1985 turned his attention to asteroids. He traveled many times to observatories abroad for his observing campaigns, especially La Silla where he discovered the majority of his objects. Overall he discovered 3 760 objects, of which 108 with others. The most famous one is 133P/(7968) Elst-Pizarro.

Hello all,

these are sad news. I met Eric several times in the last 2 decades of the last century when he was observing minor planets with the 1m-telescope at Hoher List observatory (017). At that time I was a younger amateur astronomer who was also guest visiting Hoher List for doing comet photography with the Askania Schmidt camera or with our own small telescopes which were housed in a small movable hut we built there. That was at times when we still used hypered Technical Pan film.
Eric already used CCD cameras and invited me to join him in the control room of the 1m-telescope. These were fruitful nights of discussion and I can say that it was him who arouse my interest in astrometry and minor planets.
I will never forget him.

Kind regards
Bernd Klemt, b. Brinkmann

Hello to all,

Eric Elst from 1986 to 2002, discovered thousands of asteroids of which 3,760 of them were definitively numbered, not to mention 108 other small planets co-discovered with others astronomers. I have kept up to date his list of 3868 definitively referenced asteroids from 2002 to this day. The last asteroid assigned to him was the West Trojan (483400) 1997 LY13. He also was honored on the asteroid (3936) Elst discovered by the Van Houten couple, other great discoverers of asteroids.

Eric was also a great musician and a philosopher attracted by the writings of the enlightenment, writings he distilled in his review "Le petit cuistre". Like others, I had met Eric for the first time in 2002 during the MACE
(Meeting on Asteroids and Comets in Europe) meetings organized by Korado Korlevic from 2002 to 2010. We had sympathized and we had been together many times during the past 20 years.

Gerard Faure

Hello all
I would like to inform you that the most prolific individual minor planet discoverer died, aged 85.
Eric W. Elst (1936 - 2022) started working at the Royal Observatory of Belgium in 1968…

     I was pleased to have met Elst at the 1991 ACM meeting in Flagstaff, who I knew not only as an asteroids/comet person, but perhaps mainly as a kindred spirit amongst us folks who do a lot of telescopic observing.  His extensive work on short-period pulsating variables, not mentioned in the obit, was a significant part of his early career.

(Comet News Service, archived PDF)

Remembering Don Machholz by Sky & Telescope


So very sad news . . . I successfully observed all 12 of his comets visually -- including multiple returns of his two periodic comets -- and had the pleasure of confirming or co-confirming four of those discoveries. I last saw him at the final RTMC gathering four years ago.

His Comet 96P/Machholz 1 has recently been imaged en route to its next perihelion passage next January. The viewing geometry is rather poor, but it may be visually detectable in the northern hemisphere's morning sky after perihelion.


I first met Don in early 1981, when I was still in the Navy, and the ship I was stationed on paid a port visit to San Francisco. I rented a car, drove down to San Jose, looked his number up in the phone book, called him up and introduced myself — and he invited me to join his then-wife Laura and himself for dinner. He had discovered his first comet (N/S C/1978 R3, O/S 1978l), which I had managed to observe once, a little over a couple of years earlier. We have remained friends ever since, and I was happy to confirm his discoveries when the occasions arose. I’m very glad I had the opportunity to see him again at RTMC four years ago (thanks, Charles!)


I first met Don when he came to New Zealand in 1986 to observe Halley's Comet. 
In 1991 a group of us travelled through the Southwestern USA on our way to the Total Solar Eclipse in Baja California,  and stayed briefly with Don and his then wife Laura.
He was probably the most passionate Comet observer I have ever met and a thoroughly likeable friend. A very sad loss. 
Rodney Austin


these are sad news, indeed.

I was lucky to meet Don at the IWCA II in Cambridge in 1999 after I had exchanged a few letters back in 1989 when I intended to start comet hunting (I was 19 then and living in a country named GDR).

Don was extraordinary as a comet hunter and as a human being. I will always remember him as friendly, open-minded and humble. Don, you went much too early!

I have attached one of the letters he sent to me in 1989. I am sure he wouldn't mind.

Send us some comets, Don!


Don's sudden passing, from COVID, came too soon.  Over 1977-1986 he was a generous contributor to Comet News Service.  In the attachment, see his accounts of telescopic meteors (CNS Issue 77-1), his first comet discovery (78-6), a prescient but premature lament for visual comet discoverers (83-4), a statistical analysis of comet discoveries by amateurs (85-2), his second comet discovery (85-2), and his homemade giant binoculars which netted that second comet (86-1).  Enjoy, celebrate Don.

I was privileged to shiver through a comet-hunting session with Don at his site atop windy Loma Prieta outside San Jose, California.  No more dogged and disciplined amateur astronomer have I met.

Per aspera ad cometas, Don.  Salute.

Dear friends of the comet ml list: I want to express my condolences to family and friends on the passing of Don Machholz. I would have to review my astrometric observations between the years 1998 and 2019 and see if I ever recorded in the OALM 844 some of the comets of this tremendous observer who recently started his "journey to the stars in a bright comet". I'm sure if.

What I can say is that when I was young I saw many times the photographs of Don's comets and they were very inspiring in my amateur observational career, as a teacher and as a technical observer in Los Molinos.
I feel that astronomers are a family that have the same diversified objective: observation, dissemination and teaching of this wonderful science of the stars and the cosmos as a whole. I wanted to express these feelings and say "thank you" to Don.
Respectful greetings to all

Jordi Camarasa and Grzegorz Duszanowicz - C/2023 V4 (Camarasa-Duszanowicz)

CBET 5315  issued on 2023, November 11, announces the discovery of a new comet discovered by Jordi Camarasa and Grzegorz Duszanowicz. This is their 1st comet.

From the discoverer:

The story of finding xkos369 - later comet C/2023 V4

From Moonbase South Observatory L87 - Grzegorz private facility located in Namibia -

a project called: "Moonbase South Observatory - Comet and Neo Searching Project" (MSO-CaNeSP) was lauched in June 2022. This project first used one, and from Sept. 2023 two telescopes with a 0.28 m main mirror (Celestron C11 - SCT) in a configuration with a Starizona Hyperstar f/1.9 and a full frame CMOS cameras with a Sony IMX455 sensor from ZWO, model ASI 6200MM-P.

A few hours before the session of MSO-CaNeSP started on Nov. 4th. Jordi prepared part of the observing plan for the scopes we use for this project. Grzegorz prepared the observatory for work and launched observation plans for both C11 scopes, also adding some new fields to search for comets in the vicinity of the Milky Way in accordance with the general plan. The data from both scopes was constantly downloaded to a computer in Sweden. This PC analyzes the data looking for potential new moving objects. Jordi usually check the obtained data processed by the Tycho program installed on it and does measurements and reports observations as well new objects, mostly NEOs to the MPC.  In the early morning on Nov 5,  the material from one of the scopes that was processed  by the Tycho program. Searching area marked as "Field-A15" showed an unknown slowly moving object that looked more like a little comet with a short tail...

Jordi did astrometrical measurements and sent the MPC report as new NEO Candidate and contacted Grzegorz. Very soon together they came to the conclusion that they were dealing with a comet because of its cometary appearance and soon sent the cometary activity report as well. Next night we could take additional pictures of this object with C14 scope also from L87. Those images showed very clear the coma and short tail.
