Talk:Vera C. Rubin Observatory

message: I see that the article was edited in November 2006, when the construction dates were updated. Still, the intro to the article has construction starting in 2010 and complete in 2013.
According to this press release at Brookhaven, announcing a $14.2M grant to the LSST, the years should be 2009 and 2012.

message: M2 has been cast and generated.  M1/M3 is currently being generated: M1 has been rough ground, and M3 is being rough ground.  It is expected to be finished in early 2012.  71.41.210.146 (talk) 06:44, 14 April 2010 (UTC)

message: I may be uninformed, but I have no idea what the term "engineering first light" means. I can guess, but would it be better if someone re-wrote this section so that it is in plain English which avoids jargon? --95.115.190.59 (talk) 00:20, 13 January 2011 (UTC)

message: I saw it described in this Symmetry article.  Apparently, it's already running the Hyper Suprime-Cam on the Subaru Telescope.

thread_title:  Note to self: LSST software is open source, worth adding to article. 

message: As a builder of LSST, I've passed this page on to our communications office to check for accuracy. We're still getting used to the new nomenclature ourselves, so I figured someone better versed in it should take a look here. One suggestion someone had was to have separate pages for VRO (the observatory itself), and LSST (the survey that will be conducted by VRO starting 2022). That could also help tidy up this page. Do other editors have thoughts on this? - Parejkoj (talk) 20:46, 9 January 2020 (UTC)
replies: text: Current articles are mixed. Sloan Digital Sky Survey and Pan-STARRS have an article on the survey and telescope(s) combined.  The Samuel Oschin telescope telescope has its own page, but there is one for National Geographic Society – Palomar Observatory Sky Survey and one for Zwicky Transient Facility as well.  Likewise there are separate articles on Hubble Space Telescope and Hubble Deep Field.  From this I would conclude that if the main use of a telescope is a survey, then the two are closely related and one article suffices.  If the telescope is used for lots of things (like Hubble), or is repurposed after the original survey completes, then separate articles are appropriate.  So I'd keep one article for now.   LouScheffer (talk) 02:22, 10 January 2020 (UTC)
replies: text: Seems separate articles on major discoveries, or images which became iconic, could eventually fit a multi-page approach. Probably depends how much new knowledge emerges from the project and how notable individual or overall discoveries become separate from the existence of the instrument itself. Randy Kryn (talk) 03:47, 10 January 2020 (UTC)
replies: text: It seems best to keep everything in one article for now, while the observatory is still under construction. But, after the survey is in progress for a while and begins to have a real science impact, then there could easily be material for separate articles on the telescope/observatory itself and on the survey and its scientific results.

thread_title:  Separate VRO and LSST pages 

message: Something I found very confusing when reading this is trying to understand exactly who owns this telescope, and how the US is building a telescope in Chile. How does the mix of private, research and government funding work? Who will own and operate it? How did they acquire the land in Chile? What is the relationship with the Chilean government? It would be great if some of these points could be clarified in the article, perhaps even in the lede. Stevage 18:49, 16 January 2020 (UTC)
replies: text: You should be able to find some of that information in the LSST Science Book and/or on one of the links on the [organization page. It would be a useful addition to the page, I agree. - Parejkoj (talk) 18:21, 17 January 2020 (UTC)

message: Hi Parejkoj, by reverting  my edit you removed a source and restored a "citation needed" tag. Please provide a reference for your insider kowledge. --Rainald62 (talk) 08:08, 22 September 2020 (UTC)
replies: text: Ah, sorry, I didn't see the CN tag there. The original text is correct, that FAQ page is just written in a confusing way. Although I now see the filter names are capitalized, which is also wrong. I'll add some cites. - Parejkoj (talk) 17:56, 22 September 2020 (UTC)

message: The Naming section of the article has an apparent inconsistency.
Current prose is:
In June 2019, the renaming of the Large Synoptic Survey Telescope (LSST) to the Vera C. Rubin Observatory was initiated by Eddie Bernice Johnson and Jenniffer González-Colón.[22] The renaming was enacted into law on December 20, 2019.[23] The official renaming was announced at the 2020 American Astronomical Society winter meeting.[12] The observatory is named after Vera C. Rubin. The name honors Rubin and her colleagues' legacy to probe the nature of dark matter by mapping and cataloging billions of galaxies through space and time.[22]
The telescope will be named the Simonyi Survey Telescope, to acknowledge the private donors Charles and Lisa Simonyi.[24]
It seems to be named both the Vera C. Rubin Observatory and also Simonyi Survey Telescope.  
Is it both at the same time?
Is it named/called different things by different political jurisdictions or different astronomical groups?
Was it perhaps named one thing at one time in history and is now named something else?
We should endeavor to improve the article and clarify this.  N2e (talk) 11:05, 19 November 2021 (UTC)
replies: text: The telescope structure is "the Simonyi Survey Telescope at Rubin Observatory", as opposed to the observatory as a whole (buildings, camera, auxtel, equipment, computers), which is "the Vera C. Rubin Observatory". In most relevant circumstances, the Rubin Observatory is what one would refer to. The naming guide makes this all clear, I hope: https://project.lsst.org/documents/name-use-guide - Parejkoj (talk) 21:35, 19 November 2021 (UTC)
