Summary

A bright green ball-shaped object with a tail was observed in Oregon in 1957. It was seen at around 3000 feet altitude and described as a luminous sphere. The witness saw it while driving uphill in a direct line of sight. Initially thought to be a flare or meteor, it was not conclusively identified.
