PROJECT 10073 RECORD CARD — 17 Jun 61

This document is a Project 10073 record card documenting an unidentified aerial phenomenon reported on June 17, 1961, at 1152Z. The sighting occurred in the Pacific region at coordinates 26:02 N, 143:10 W. A single object was observed for a duration of 10 seconds, traveling on a flat trajectory with a heading of NNE. The witness reported that the object changed brightness in four distinct stages. The report was transmitted via a CIRVIS (Communication Instructions for Reporting Vital Intelligence Sightings) message, which was evaluated by military authorities and determined to pose no threat. The official conclusion recorded on the card suggests that while the duration of the sighting is indicative of a meteor, the specific behavior of the object—specifically the changes in brightness—is inconsistent with such an explanation. Consequently, the case was classified as having insufficient data for a definitive evaluation due to the brevity of the initial report. The document includes both the standardized record card and a copy of the incoming staff message from the Hawaii Air Defense Division at Kunia Annex, which was distributed to various military commands including CINCPACAF, CINCNORAD, and MATS.
