Echo II satellite seen in the Pacific

Summary

A report from November 17, 1964, describes the observation of a bright object in the sky over the Pacific, near the coordinates 30°N 138°W. The object was moving slowly toward the southeast at a high altitude, appearing like a star. Although no photos were taken and the duration wasn’t reported, analysts concluded it was the ECHO II satellite, an inflatable sphere used for communications. The clear weather and the object's trajectory supported this identification.

The report was shared with several military and intelligence agencies, including the Air Force and Navy, as part of standard procedures for analyzing unidentified aerial phenomena. Despite no physical evidence or additional testimonies, the alignment with ECHO II's known orbit led to the conclusion that it was not an unexplained phenomenon. This case reflects how observers of the time tried to distinguish between natural objects, satellites, and potential UFO sightings.
