I put this article in two constellation categories, Circinus and Centaurus. If my calculations are correct, the semiplane αB1875=14h32m slices right through RCW 86, leaving part of it in Circinus and part in Centaurus. I'm a bit surprised that I haven't found anything about this on the Web; surely I can't be the first person to have noticed that RCW 86 straddles a constellation boundary? -- Evil-mer0dach 23:24, 7 February 2007 (UTC)
I would like to see some less technical commentary in the X-ray source section (i.e. why is it significant?) Kevink707 ( talk) 15:12, 8 April 2011 (UTC)
This Wikipedia article says that it was visible in the night sky but the a BBC television program called Cosmos (currently available on Netflix) said it was visible to the Chinese during day. — Preceding unsigned comment added by 66.194.235.133 ( talk) 20:54, 25 October 2011 (UTC)
When was the Chinese observations first scientifically verified and by whom ? -- 79.168.11.181 ( talk) 13:30, 27 December 2011 (UTC)
The proper motion of Proxima Centauri is quite large, and in the "right" direction, such that at the time this supernova was observed, it would be been "almost" line of sight with Promixa. That is probably only a "cosmic coincidence" :D — Preceding unsigned comment added by 58.167.165.70 ( talk) 05:28, 14 January 2019 (UTC)
