Is the following statement: "highest relative magnitude stellar event in recorded history" true only from a Visual spectrum perpective? I think much brighter events occured since, like GRBs and magnetar Flashes along other spectrum lengths
"Highest relative magnitude" is ambiguous - do you mean "brightest in terms of peak apparent visual magnitude" or "maximum change from pre-supernova magnitude to peak magnitude" ? Varunbhalerao 06:26, 30 April 2006 (UTC)
It is not entirely clear if the dates given are Julian or Proleptic Gregorian dates. grr 00:37, 17 October 2007 (UTC)
Image:Tunc Tezel SN 1006.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

I am unsure of the meaning of the reference "According to Songshi in the section of 56 and 461" this does not make a lot of sense - at least to me. Also, I have not encountered a reference to a constellation named Di - it is not one of the recognised stellar constellations in western cosmography - if there is such a constellation in eastern tradition - could a cross reference be made?

Hello,
the French article states that it was a Type II supernova due to the fact that it was visible for one year (La supernova est restée visible plus d'une année, ce qui en fait probablement une supernova de type II.). The English article mentions a Type I supernova. Poppy (talk) 10:29, 29 August 2008 (UTC
In 1006, the Egyptian astronomer Ali ibn Ridwan observed SN 1006, the brightest supernova in recorded history, and left a detailed description of the temporary star. He says that the object was two to three times as large as the disc of Venus and about one-quarter the brightness of the Moon, and that the star was low on the southern horizon. Monks at the Benedictine abbey at St. Gall later corroborated bin Ridwan's observations as to magnitude and location in the sky... why are u guys posting false info? User:69.209.142.230 8 March 2009
I have modified the lead to change intensity to "visual magnitude", linking to "apparent magnitude". Intensity is a term that has precisely defined meanings in numerous scientific and technical contexts, but not in reference to the visual appearance of stars. "Apparent magnitude" describes brightness as seen at the observer's distance, without regard to the actual distance to the object. ("Absolute magnitude" is what the apparent magnitude would be at the standard distance of 10 pc.) A further issue relates to color; "V" in the older broadband UBV (Ultraviolet/Blue/Visual) system is probably the best choice here, as the observations were of course all visual. (Of course good theoretical modeling of the explosion may estimate the color in other bands, but that is another layer of complexity.) Wwheaton (talk) 23:37, 30 April 2010 (UTC)
A Type Ia SN should leave behind its more or less normal companion, which should have been expanding towards its red giant phase at the time of the outburst. Probably the outer layers of that star would have been stripped off by the explosion, leaving some kind of peculiar core, possibly similar to a white dwarf. Its composition might be abnormal if it was able to capture much of the products of the detonation, "nuclear ash". If this object has been identified or characterized, it would be interesting to report it here. Wwheaton (talk) 15:49, 2 May 2010 (UTC)
I don't think that Wikipedia should be stating without qualification that the Hohokam White Tanks petroglyph may represent this supernova. The petroglyph is an otherwise undated, crude drawing of a scorpion and a star, which only can be considered to represent SN 1006 if one assumes that native Americans interpreted Scorpio identically to European astrologers. I think the whole section regarding the petroglyph should be removed. —Preceding unsigned comment added by 129.174.114.104 (talk) 18:02, 9 July 2010 (UTC)
Hello! This is a note to let the editors of this article know that File:Supernova Remnant SN 1006.jpg will be appearing as picture of the day on September 12, 2013. You can view and edit the POTD blurb at Template:POTD/2013-09-12. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 23:15, 28 August 2013 (UTC)
There are several references that do not make sense within the content of this article, e.g. "The supernova would have been very low in the sky there". Where? Or: "the "sometimes contracted, diffused, extinguished" remarks quoted above" - quoted where? JEH (talk) 02:10, 12 September 2013 (UTC)
The "Effects on Earth" section ends "See the above-referenced article for more detail." There are now several references in the preceding text, however. If I could identify the citation, I'd just fix it. I've contacted the original editor of the section, but can anyone clean this up?--Wetman (talk) 20:05, 30 April 2014 (UTC)
I have just read this article on SN 1006A, and find that it needs a severe edit to fix and improve the quality of this article. It is clear that most of the text is based on second or third hand sources, which has left the text as a tangled mess. The principal expert on historical supernova is F. Richard Stephenson, which is not featured here nor properly in the article History of supernova observation. Editors should read this article "SN 1006AD The Brightest Supernova" (2010) , which although an general article, contains most the actual historical observations, translations and Stevenson's formal analysis.
Importantly;
Thanks.

The infobox and template:sky both give the J2000 coords as 15h 2m 8s, -41° 57′, without reference.
Simbad has similar but slightly different coords: 15h 02m 22.1s -42° 05′ 49″ (which is the location shown in Uranometria 2000.0).
What puzzles me is that either position is just across the border in Centaurus (about half a degree east of κ Cen).
So why does everyone (including Simbad) call it the "Lupus SN"?
Also, the article says it is east of Lupus and west of Centaurus.
Presumably the opposite is meant.

That article puts the extreme limit at 1000 light-years. This article states the star remnant in 7,200 light-years distant. What's the relevance? 50.111.30.135 (talk) 06:32, 30 April 2022 (UTC)
Is it true? 20 parecs =~ 65.23 light-years = approx. distance moved over about 1017 years. Which is 3.83463e+14 miles in 1017 years, an average speed of about 43 million mph. This might an interesting tidbit to add. — Preceding unsigned comment added by Capricio (talk • contribs) 06:03, 13 September 2023 (UTC)
