Strange Light in the Sky
Huge Greenish Formation, Possibly Gascous, Observed by Many
A huge greenish light, appearing to be a formation of some gaseous substance in the shape of a great ball, was visible in the heavens southeast of Tulsa last night for about 15 minutes shortly after 11 o’clock.
Whether it was a meteor cast off by a star or a peculiar collection of gas in the air is not known. It attracted considerable attention in Tulsa, a number of people who had seen it phoning The World. No reports were received by wire of the phenomenon being observed in other towns.
