A summary of a NASA debrief says Stafford and Cernan saw flashing lights and flashes during Gemini 9. The scan provided does not include a readable account of the sighting.
A NASA file compilation surrounding the June 16, 1966 scientific (OSSA) experiments debriefing of Gemini IX-A astronauts Thomas Stafford and Eugene Cernan, assembled by Jocelyn R. Gill of the Manned Flight Experiments Office. The bulk of the legible material consists of internal memoranda, routing slips, and telegraphic messages documenting the status and results of the mission's scientific experiments (S-1 zodiacal light, S-10/S-12 micrometeorite collection, S-11 airglow horizon photography, S-5/S-6 synoptic photography) and related planning correspondence with NRL, GSFC, MSC and other bodies. The manifest states that pages 2-5 contain the astronauts' accounts of 'flashing lights' and 'sparkles' observed during the mission, but the extracted text for those pages is blank or illegible OCR, so the UAP-relevant observations are not recoverable from the text layer. Much of the remaining document is heavily garbled OCR of handwritten notes.
Per the manifest description, pages 2-5 of this document contain Gemini IX-A astronauts Stafford and Cernan's debriefing accounts of 'flashing lights' and 'sparkles' observed during the mission. The extracted/OCR text for those pages is blank or illegible, so the specific content of those accounts could not be recovered from this document's text layer.
"The efforts to dislodge the shroud from the ATDA, (called by Tom Stafford as "an angry alligator,") were in vain so docking with the ATDA was scrubbed from the mission."
Speaker: Jocelyn R. Gill (quoting Tom Stafford)
Why it matters: Origin of the famous 'angry alligator' description of the failed-shroud ATDA target vehicle.

"Features show up in these pictures which do not appear on any existing map; for example, a glacial lake in the Andes which do not appear on any existing maps. The Peruvian Embassy has been informed of this lake which may portend an avalanche hazard for villages located below."
Speaker: Jocelyn R. Gill
Why it matters: Synoptic photography from orbit revealed a previously unmapped glacial lake; flagged as a possible avalanche hazard and reported to the Peruvian government.

"At the start of the experiments they had 50 lbs. of fuel left and at the end, so it is reported, they still had 50 lbs!!"
Speaker: Jocelyn R. Gill
Why it matters: Unusual emphasized note that fuel quantity was unchanged across the experiment period.

"TALK ABOUT AN ACE IN THE HOLE! CONGRATULATIONS TO GEMINI IX ON CARRYING OUT A MOST DIFFICULT AND TRYING MISSION. YOUR PATIENCE AND COURAGE WERE REWARDED."
Speaker: Willis B. Foster, Director, Manned Flight Experiments Office
Why it matters: Post-mission congratulatory telegram to the crew.

"On Tri-X these are the best pictures yet of the zodiacal light surpassing the results achieved on Gemini V."
Speaker: Jocelyn R. Gill
Why it matters: Assessment of S-1 zodiacal light photography results relative to a prior Gemini mission.

This is a large NASA administrative file folder centered on the Gemini IX-A scientific experiments debriefing (June 16, 1966), not a dedicated UAP report. The corpus title and manifest tie it to astronaut accounts of 'flashing lights' and 'sparkles,' but those pages (2-5) are not legible in the extracted text; the recoverable content is almost entirely OSSA experiment status memos, routing slips, and telegrams. OCR quality is poor for the many handwritten pages. Confidence reflects strong entity/context extraction but inability to verify the core UAP observations from the text.
Astronauts Thomas Stafford and Eugene Cernan, members of the Gemini 9 crew.
The summary says it contains reports of flashing lights and flashes. The supplied scan does not include a readable account of the sighting.
No. Neither the summary nor the readable material explains what caused them.

During the Gemini 9 mission, Thomas Stafford and Eugene Cernan saw flashing lights and flashes in space, according to a summary of NASA’s debrief with the two astronauts after the flight.
They were in space from June 3 to 6, 1966, on a mission that included a spacewalk and experiments. But the summary devotes only a few words to the lights. The transcript is supposed to contain their descriptions, but the supplied text doesn’t reveal what they actually said.
Gemini 9 launched in June 1966. After the mission, NASA held and recorded a debrief with Stafford and Cernan. According to the document’s summary, certain pages include the astronauts’ reports of “flashing lights” and “flashes.”
Those are the only details about the sighting: two crew members in space noticed lights and described flashes. The summary doesn’t say whether they saw them together, whether the lights moved, or how long the sighting lasted.
The document is a transcript, a written record of a conversation. But the text provided does not include the discussion of the lights. Much of the scan is blank or garbled, making the account of the sighting impossible to read.
The legible pages deal mainly with experiments: photographs, test results, and particles collected in space. They explain what the crew did on the mission, but not what the two astronauts saw. So their words cannot be quoted beyond the brief description in the summary.
The readable material offers no details about the lights’ appearance or when they showed up, and no ordinary explanation for the sighting. The summary itself suggests no cause, so it’s impossible to determine what produced them.
The transcript promises a more detailed account, but in the scan available here, the lights themselves have almost vanished.
