Items for copyedit

 * An alternative name for the constellation, Phoenicopterus (Latin "flamingo"), was used briefly during the early 17th century, seen in the 1605 work Cosmographiae Generalis by Paul Merula of Leiden University and a c, 1625 globe by Dutch globe maker Pieter van den Keere.
 * What is "a c"?
 * supposed to be "c." - hence circa. I can't think of an easier way to say it. Cas Liber (talk · contribs) 09:19, 20 February 2014 (UTC)


 * As both of these people worked with Plancius, astronomer Ian Ridpath has reported the symbolism likely came from him originally.[2]
 * Unclear pronoun antecedents. Does "both of these people" mean Merula and van den Keere? Does "from him" mean from Plancius?
 * yes- was using pronouns to reduce repetition - I thought the structure and meaning made it unambiguous... Cas Liber (talk · contribs) 09:19, 20 February 2014 (UTC)


 * In Central Australia, the Arrernte and Luritja people living in on a mission in Hermannsburg viewed the sky as divided between them, east of the Milky Way representing Arrernte camps and west denoting Luritja camps.
 * "living in on a mission" is awkward phrasing.
 * typo - "in" removed Cas Liber (talk · contribs) 09:19, 20 February 2014 (UTC)


 * Grus is located too far south and hence remains below the horizon for observers in the British Isles and northern United States, though can be easily seen from Florida or California.[9]
 * Missing word "it."
 * Southern California?
 * "it" added ...possibly southern but source says what it says :( Cas Liber (talk · contribs) 09:19, 20 February 2014 (UTC)


 * Also known as Al Dhanab, it has finished fusing its core hydrogen and begun cooling and expanding,
 * Sentence parallel structure. Should be "has begun".
 * added Cas Liber (talk · contribs) 11:21, 20 February 2014 (UTC)


 * The system is poorly known,[22] though the donor star has been calculated to be of spectral type F5V.
 * Consider alternative phrasing, like "poorly characterized."
 * poorly understood? Cas Liber (talk · contribs) 11:21, 20 February 2014 (UTC)


 * RZ Gruis is a nova-like binary system of apparent magnitude 12.3
 * "Nova-like"? Do you have a better phrasing?
 * I removed " nova -like" as  cataclysmic variable  mentioned soon afterwards Cas Liber (talk · contribs) 11:21, 20 February 2014 (UTC)


 * The system is poorly known,[30]
 * Consider alternative phrasing.
 * not sure how that happened that it got reduplicated - already fixed Cas Liber (talk · contribs) 11:23, 20 February 2014 (UTC)


 * CE Gruis (also known as Grus V-1) is a faint (magnitude 18–21) star system also composed of a white dwarf and donor star, in this case the two are so close and fused into orbit facing one another.
 * Run-on sentence.
 * semi-coloned Cas Liber (talk · contribs) 11:23, 20 February 2014 (UTC)


 * Gliese 832 is a red dwarf of spectral type M1.5V and apparent magnitude 8.66 located only 16.1 light-years distant, hence one of the nearest stars to the Solar System.
 * Run-on sentence.

 * A Jupiter-like planet with an orbital period of 9.4±0.4 years was discovered in 2008.[39]
 * Orbiting around what?
 * Gliese 832 - clarified Cas Liber (talk · contribs) 20:38, 20 February 2014 (UTC)


 * Around 3000 light-years distant, it is expanding at a rate of 50 kilometres a second, one of the fastest of all planetary nebulae.[41]
 * One of the fastest rates of expansion?

 * (Question only. No action necessarily needed.) Does the article as a whole follow British or U.S. spelling? Does a template need to be placed on the Talk page?
 * hmmm, hadn't thought of that - as an Australian I'd go with British as default, so likely that. Cas Liber (talk · contribs) 20:38, 20 February 2014 (UTC)


 * NGC 7552 and 7582 are exhibiting high starburst activity, thought to have arisen because of the tidal forces from interacting.[44]
 * Awkward sentence. Please rework.
 * rejigged Cas Liber (talk · contribs) 20:38, 20 February 2014 (UTC)


 * It has a fast counterrotating stellar core, and stellar shells and ripples in its outer region.[46]
 * ...with shells and ripples...
 * trimmed Cas Liber (talk · contribs) 20:38, 20 February 2014 (UTC)


 * SN 2001ig, one of the two supernovas within NGC7424, was discovered in 2001 and classified as a Type IIb supernova, one that initially shows a weak hydrogen line in its spectrum, but whose H emission later becomes undetectable and is replaced by lines of oxygen, magnesium and calcium, as well as other features that resemble the spectrum of a Type Ib supernova.[citation needed]

Items for fact-check

 * Covering 366 square degrees, it ranks 45th of the 88 modern constellations in size and covers 0.916% of the night sky.[7]
 * Compare with 0.89% in 88 modern constellations by area. Stigmatella aurantiaca (talk) 08:47, 20 February 2014 (UTC)


 * I checked 88 modern constellations by area on a spreadsheet. The numbers in the table are internally consistent, with Grus 0.886% of the total solid angle which sums to very close to 4π (5 significant figures). Whether the numbers in this table are right is a different matter, of course. Stigmatella aurantiaca (talk) 11:29, 20 February 2014 (UTC)


 * The correct figure is 0.887%. All sources that I have checked agree, including Philip M. Bagnall, The Star Atlas Companion: What you need to know about the Constellations which was cited incorrectly in the text. Stigmatella aurantiaca (talk) 21:48, 20 February 2014 (UTC)


 * whoops - fixed now. Not sure how that happened - I think I must have cut-and-pasted the text from another constellation but accidentally not changed that like I changed everything else..... Cas Liber (talk · contribs) 03:18, 21 February 2014 (UTC)


 * See also here http://www.ianridpath.com/constellations1.htm. 81.178.180.252 (talk) 10:06, 1 April 2014 (UTC)


 * that is very helpful Cas Liber (talk · contribs) 10:37, 1 April 2014 (UTC)

Spot-checked references

 * The 15-20 references that I spot-checked looked appropriately cited. Ridpath is sufficiently notable that use of his self-published web site should be acceptable. Stigmatella aurantiaca (talk) 21:26, 20 February 2014 (UTC)


 * Thank you. May I note that Jim Kaler's site on Stars is also self-published but you do not choose to describe that as such. Ian 81.178.180.252 (talk) 10:07, 1 April 2014 (UTC)
 * Hmmm, not sure as it is hosted by University of Illinois....will ask and see how we should describe it. Cas Liber (talk · contribs) 10:25, 1 April 2014 (UTC)
 * One way or another, James B. Kaler counts as an expert in his field. Stigmatella aurantiaca (talk) 10:54, 1 April 2014 (UTC)
