TL;DR
Found official records I did not know about that corroborates the attention the US government gave to the "Green fireball" phenomenon observed in Los Alamos, specifically near the Sandia facilities circa 1949.

The phenomenon of green fireballs over Sandia facilities in Los Alamos from 1947-1950 is, apparently well known. This document mentions the involvement of top scientists such as Edward Teller and the AFSWP (military division created just then by James Forrestal and others to support the nuclear development endeavours if the US) in trying to study the phenomenon in more depth.

Thanks to user u/ASearchingLibrarian who pointed me in the right direction to find this. There is a lot more information about this from as I came to learn since, but this is still an interesting bit of evidence and history and the way I stumbled upon this was totally independent and unconnected to these sources, which I believe means there is some meat to it.

Other sources here, from which, at least the interview with Doyle Rees (Col. USAF, ret.) is worth a read (https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=htt…

Sorry for the re-post, I should have added the pictures the first time.
