Blue glow sighted by officers in Naperville

Summary

In March 1963, two Naperville, Illinois police officers reported a continuous blue glow moving from northwest to southeast. The object had no visible tail, which raised curiosity and confusion. The sighting was officially recorded but no photos or radar data were taken. The phenomenon was labeled as "insufficient for evaluation," meaning no clear conclusion was reached about its nature.

This case is part of a series of UFO reports from the time, where authorities tried to understand unexplained aerial phenomena. Although all possibilities weren't ruled out, the lack of concrete data prevented further analysis. The report was sent to the Air Force, which was actively studying unidentified objects during that era.
