DISCLOSURE / FILELANL AT-6 Physicist Briefs Pajarito Astronomers 1986
DOE-UAP-D003, Pajarito Astronomers Invitation, 1986
A 1986 Pajarito Astronomers club letter announcing a UFO-focused presentation by Los Alamos National Laboratory physicist Dr. John Warren — an event LANL has no institutional record of.
Brief
Dated May 20, 1986, this single-page letter from the Pajarito Astronomers of Los Alamos, NM announces a May 29 talk by Dr. John Warren of LANL's AT-6 division, titled 'Why Should a Scientist be Concerned about UFO's?' The meeting was held at Fuller Lodge and was not an official LANL event. The laboratory has no institutional record of the subject matter discussed. Club officers are identified by LANL mailstop codes, indicating the membership substantially overlapped with laboratory personnel.

Key points
- Dr. John Warren, affiliated with LANL's AT-6 division, was scheduled to present on the scientific relevance of UFOs to an amateur astronomy club in Los Alamos — not in any official LANL capacity.p.1
- The presentation title frames UAP as a legitimate subject for scientific inquiry, which was an unusual posture for a public forum in 1986.p.1
- LANL has no official record of the content of the presentation, leaving the substance of a weapons physicist's UFO talk entirely outside the institutional archive.p.1
- Club officers are listed by LANL internal mailstop codes (MS K553, SE531, SF665), establishing that the Pajarito Astronomers were effectively a subset of LANL's workforce, not a general-public organization.p.1
- The meeting was scheduled for Thursday, May 29, 1986, at 7:30 p.m. in the Ranch Room at Fuller Lodge, Los Alamos.p.1
- The event was explicitly not hosted by Los Alamos National Laboratory despite the speaker holding an AT-6 affiliation.p.1
Verbatim
Our next meeting will be Thursday, May 29, 1986, in the Ranch Room at Fuller Lodge, at 7:30 p.m.

Most interesting
- AT-6 is a weapons physics division at Los Alamos — a scientist from that group presenting on UFOs to a civilian astronomy club in 1986 sits at an unusual intersection of nuclear-weapons research and UAP interest.
- The Pajarito Astronomers used LANL internal mailstop codes to identify their club officers, meaning this nominally civilian astronomy club was a satellite community of laboratory employees.
- LANL's stated absence of any record of what Warren discussed leaves the content of a weapons physicist's UFO talk entirely unaccounted for in the institutional archive — this letter is the only surviving official trace.
- Fuller Lodge is a 1928 log building that served as the social center of the original Manhattan Project community, giving the setting an additional layer of historical weight.
- The presentation was framed as a scientific-justification argument — why scientists should care — not as a sighting report, suggesting Warren anticipated skepticism from a technically trained audience and structured his talk accordingly.
