Image for portal spaceflight boxEdit

Hi! Thanks for your help while I was struggling with the images not appearing properly in the portal spaceflight box. Another person thought to ask about the trouble Wikipedia:Village_pump (assistance)#image in a portal box. The answer given there points to a reasonable work-around, which I'm going to try. If the image still doesn't show up correctly ... I'm gonna' scream! (sdsds - talk) 03:22, 16 September 2007 (UTC)

Image:Comet tails animation.gifEdit

I've removed the speedy deletion tag from this image, as it does not seem to meet any of the criteria for speedy deletion. Lack of accuracy is not a valid reason. I suggest you take it to Wikipedia:Images and media for deletion instead. – Tivedshambo (talk) 16:08, 16 January 2008 (UTC)

You should not have such an offensive Userbox on your stupid userpage. —Preceding unsigned comment added by Alex1996Ne (talkcontribs) 01:07, 5 February 2008 (UTC)

Rigel apparent magnitudeEdit


I see that on Rigel, you changed the apparent magnitude with comment: visual magnitude from Hipparcos Catalogue, the most precise photometric catalogue.

However, the citation on apparent magnitude still points to Simbad. Please provide a replacement inline citation for your new source of 0.18 over the simbad 0.12 value. Also, can you give a cite which supports Hipporcos being more accurate than Simbad?



The Hipparcos Catalogue is astrometric and photometric catalogue based on observations of satellite Hipparcos. Simbad is astronomical database which include information from many catalogs, including Hipparcos. Value 0.12 is taken from Yale Bright Star Catalogue version 5 (BSC5). But in Hipparcos catalogue there is 0.18 value. Both catalogs may be accessed from Simbad/VizieR. It is considered that Hipparcos is most precise in both photometry and astrometry, see for example Astrometric and photometric catalogs recommended by USNO. See also Comparison of recommended astrometric and photometric star catalogues. — Chesnok (talk) 08:08, 12 April 2008 (UTC)

Comet LexellEdit

Can you leave a comment on the rationale of splitting Comet Lexell from Anders Johan Lexell? Leave a comment at Talk:Anders Johan Lexell. At present there is no information on the comet to be split out. Cheers. -- Alan Liefting (talk) - 05:50, 24 July 2008 (UTC)

I think that each comet described in Wikipedia must have a separate page. — Chesnok (talk) 10:35, 13 September 2008 (UTC)

Periodic comets?Edit

You seem to know what you're doing with the List of periodic comets, so this change puzzles me: what did you mean by "De facto unnumbered short-periodic comets with P > 30 years have [a] "C" prefix."? That claim is patently false, as there are several P/ comets with periods in the 30 to 200 year range: 54 out of 416 in fact. They range from P/2002 CE10 to P/1937 D1. Please explain. Urhixidur (talk) 02:30, 9 September 2008 (UTC)

Both official (and most respectable) sources (Harvard Center for Astrophysics, NASA JPL Small-Body Browser) show C/2007 S2 (Lemmon) instead of P/2007 S2 (period is 44.4 years)[1] [2], C/2008 E1 (Catalina) instead of P/2008 E1 (period is 34.9 years)[3] [4] C/2002 CE10 (LINEAR) instead of P/2002 CE10 (P is 30.8 years)[5], C/1937 D1 (Wilk) instead of P/1937 D1[6] (last two comets have no pages at CfA because they are not observable now).
However, P/2005 T4 SWAN (P is 28.6 years)[7], P/1997 B1 (Kobayashi) (P is 25.2 years)[8], etc. You can see 30-years-border in assigning "C" or "P" prefixes for unnumbered periodic comets.
Are you convinced now? Excuse my English. — Chesnok (talk) 15:15, 12 September 2008 (UTC)

Not quite: has P/2007 S2 (Lemmon 1), P/2008 E1 (Catalina 9), P/2002 CE10 (LINEAR 34), P/1937 D1 (Wilk 1). The Planetary Data System (PDS) is just as reliable as CfA or JPL SSD, so one can only assume this is a matter of update/refresh time. Urhixidur (talk) 17:09, 15 September 2008 (UTC)

I've tried rephrasing what you explained, with links. Take a look. Urhixidur (talk) 17:19, 15 September 2008 (UTC)

OK, it appears more correctly. — Chesnok (talk) 19:18, 15 September 2008 (UTC)

Kreutz SungrazersEdit

1) I removed Category:Kreutz Sungrazers from Sungrazing comet article because such a categorization is misleading. Not all sungrazing comets are Kreutz Sungrazers. Therefore Sungrazing comet article should not be a part of that category.
2) Regarding two article about Kreutz Sungrazers comets, which I removed from Category:Comets, I should explain that I tried only to make categorization consistent. All other Kreutz Sungrazers except those two do not belong to the Comets category. So if you think that the Kreutz comets should be in both categories, please add Comets category to all other Kreutz Sungrazers articles, otherwise the categorization is illogical.

Ruslik (talk) 19:05, 18 September 2008 (UTC)



While I agree that it is not of Wikipedia's resort to "clean up" software, astronomical or other, I do believe that it was informative to write in the article about Comet 85P/Boethin that StarryNights software wrongly lists it as Boethin (85P), as it shows people the proper way to refer to the comet (or to any other).

I was a corrector for an astronomy book a few years ago, and the author was using the wrong way to refer to comets (a mumbo-jumbo of Halley (1P), Halley/1P and 1/P Halley for example). Being an amateur astronomer and not a professional, he did not know better, just because he never came across any reliable source of information saying that comets are designated by a sequential number; a one-letter code for whether they are periodic (P), one-time visitors (C), disappeared (D) or destroyed (X); a forward slash; and either their common name if any, or the year-letter-number code of their discovery date.

I believe that Wikipedia, while not currently seen as a reliable source by many, should endeavor to become the most reliable source there is.

But that is just my opinion. I'd like to know yours.

CielProfond (talk) 01:09, 31 October 2008 (UTC)

Yes, I agree with you. It is disgusting to look on such erroneous writings. I reverted my edit. — Chesnok (talk) 08:16, 31 October 2008 (UTC)
Haha, well, I didn't necessarily mean for you to revert your edit, but just for your opinion about that issue, and maybe we could have worked out a possible alternate solution. It might only be a matter of time before someone else does the same edit again anyway... CielProfond (talk) 01:23, 1 November 2008 (UTC)

Kreutz SungrazersEdit

I wondered why you reverted my addition of the pronunciation file until I checked the edit. I accidentally forgot to enter the right file information when I copied the template code. I've corrected my mistake. - Mgm|(talk) 14:11, 2 November 2008 (UTC)

Category: Kupier quadrangle at bs.wikiEdit

You have change the category twice. At first it was a edit of your bot you revert and at second a edit of silvonenbot. Can i know the reason? Please answer here. --Seha (talk) 17:43, 7 January 2009 (UTC)

You don´t need to be so loud like: Please learn astrology... The edit was requested here because the Kupier quadrangle and Kupierov pojas means the same just translated! It seams to me there is a problem of false category at our wiki. No need for such comments! --Seha (talk) 18:15, 7 January 2009 (UTC)

Now I saw it´s a not existing category on en wiki: Category:Kupier belt. Now your edit has a sence even for one who is not an astronomer. :) Write a comment when you change so we don´t need to revert by vandalism. --Seha (talk) 18:24, 7 January 2009 (UTC)

Because I don´t know the subject I asked you as you can see above. For me, who don´t have any knowlage of astrology and astronomy, it was be the same. That´s why I asked for an answer. There is no reason for such erruptions from your side. But as a sysop of there is a reason enough for me, to find out why someone change this interwiki twice and more witout any explanation. As you can see there is a summary line down under and if you use it, on a foreign wiki, we (the sysops without knowlage) can know why you have done it. Regards --Seha (talk) 19:45, 7 January 2009 (UTC)



I've unlocked your bot since there is a description on it's user page. Our policy regarding global bots has changed recently. It seem the tool you indicates me is not up-to-date.

DirlBot on fiwikiEdit

Hello, you shouldn't be doing 'cosmetic changes' with your both on fiwiki. The bot moves e.g. {{Link FA}} templates where they shouldn't be. I hope this will be fixed in pywikipediabot some day. — str4nd 18:13, 25 June 2009 (UTC)


Please note that wikipedias and wiktionaries have very different rules. Could you cancel your changes on Мордвин‎ on the Russian wiktionary? I tried, but was not very successful... Lmaltier (talk) 15:34, 17 July 2009 (UTC)


Hello Chesnok. If Hale-Bopp came to perihelion in 1997 and has an orbital period of 2520 to 2533 years, how did you calculate the next perihelion being near 4390? I see 1997+2533=~4530. I know that in March 1997 it was shown to have an orbital period of 2380 years, but the comet had not even come to perihelion yet, so that calculation lacked the follow-up observations. -- Kheider (talk) 01:36, 18 December 2009 (UTC)

The Solar System is not a two-body system. The gravitational perturbations from Giant planets will lead to changing (shortening in our case) of semi-major axis and therefore the period of comet Hale-Bopp. The next apparition of the comet, especially long-period comet, cannot be calculated from a momentary value of orbital period. The time of previous and the next apparitions can be estimated using an "original" and "future" 1/a values that are often given with an orbital elements. — Chesnok (talkcontribs) 07:25, 18 December 2009 (UTC)
I have loaded Hale-Bopp into Solex 10 and produced an estimated year of 4385. -- Kheider (talk) 09:20, 18 December 2009 (UTC)

Edits on Dutch nl:wpEdit

On the Dutch wikipedia (nl:) you recently edited numerous articles of Messier objects like here where you removed the "Messier0034" catsort. This has resulted in the objects no longer appearing in their correct order in the categories they are listed in. For instance Messier 100 now sorts ahead of Messier 34. Could you please double check your edits on nl:wiki and repair the catsort where needed? Thank you, --Kalsermar (talk) 15:08, 18 January 2010 (UTC)

File:Orbits of periodic comets.svgEdit

Hi. I'm in the middle of an FAC for Halley's Comet and the image review has tagged one of your uploads. Specifically, it claims that it "needs a verifiable source per WP:IUP. For self-made images, this would be an explicit assertion of authorship. Source for the orbital information should also be provided." If you could provide that information as soon as possible I would greatly appreciate it. Thank you. Serendipodous 16:13, 19 January 2010 (UTC)

Uklanjanje bot zastavice / Removal of bot flagEdit

(Bosanski) Želim da vas obavijestim da je se na donijela odluka da se uklone bot zastavice kod neaktivnih i/ili interwiki botova. Vaš bot spada u najmanje jednu od ove dvije kategorije. Ova odluka je donešena zbog zbivanja oko Wikidata koje je dovelo do toga da su interwiki botovi postali nepotrebni. Ako želite da zadržite vašu bot zastavicu onda možete podnijeti taj zahtjev ovdje sa dodatnim informacijama o poslovima koje bi bot obavljao i na koji nacin. Imajte na umu da ovo treba da bude konkretan i koristan posao za zajednicu da bi se zastavica zadržala. Ako imate bilo kakvih pitanja kontaktirajte me na mojoj stranici za razgovor. Ukoliko ne reagujete na ovu poruku će se uklanjanje zastavice izvršiti nakon nekoliko sedmica. Međutim, uvijek ste dobrodošli da podnesete novi zahtjev za bot zastavicu.

(English) I want to inform you that on there has been a voting that resulted in accepting the removal of bot flags for inactive and/or interwiki bots. Your bot has been identified to meet at least one of these criteria. This decision has been made due to the new developments with Wikidata by which all interwiki bots have become unnecessary. If you want to keep your bot flag, then please report that here by indicating what new task your bot will be performing and how this will be done. Note however that this has to be a concrete and useful task for the community before it will be accepted. If you have any questions, please let me know on my talk page. In case of no response, the removal of the bot flag will be performed within a few weeks from now. However, after that period you are always welcome to file a new request for a bot flag.

Inactive bot on Latvian WikipediaEdit


As a bureaucrat on Latvian Wikipedia (lvwiki), I was checking the activity of the bots, and noticed that yours had been inactive from at least September 2013. It is not reasonable that an unmonitored account keeps a bot flag, as it may be more easily hacked. If you have any future plans for bot running or want to keep this flag for some other reasons, please make a note at this table. You can also contact me directly via my user talk at User talk:Edgars2007.

If you have no objections or we won't receive any response for a month, we will remove bot flag. Thanks a lot for your previous contributions! --Edgars2007 (talk/contribs) 08:40, 27 May 2018 (UTC)
