Summary

A civilian in New York reported a round object with something hanging below, drifting slowly eastward. The report concluded it was likely a radiosonde balloon released from Idlewild about 15 minutes earlier. No photos were taken, but binoculars were used. The object reflected sunlight and moved in a straight path, consistent with a balloon. Lack of color details made the evaluation tricky, but weather data and timing align with a routine launch.
