Satellite sighted from a British ship

Summary

In June 1963, an observer aboard the British ship MS Ascanius recorded multiple sightings of an object believed to be the satellite ECHO I. The observations occurred during a voyage from Japan to California, with the object seen on different dates and times, exhibiting a brightness similar to the star Vega. Although the initial report did not include photographs, the data matched the known trajectory of the satellite, leading to the conclusion that it was likely ECHO I. The report highlighted the consistency of the sightings, supporting the identification of the object as a satellite in orbit.

The crew of the Ascanius recorded details such as geographic position, time, and direction of the object, allowing for an accurate evaluation. NASA and other agencies received these data for analysis, and it was concluded that there were no indications the object was a balloon, an aircraft, or an unknown astronomical phenomenon. This case is an example of how data collected by civilian observers contributed to the understanding of satellites in orbit during the 1960s.
