OBSERVATION READY TO RECORD METEOR PATHS

Twenty-four cameras of the Harvard Observatory, stationed at three points in the near vicinity, will be trained upon the heavens tonight, at the start of a three day observation of the yearly appearance of the Leouid meteors.

The Harvard Observatory will post watchers from midnight to dawn at the Oak Ridge Observatory at Harvard Massachusetts; the Blue Hills Observatory. Milton; and at Bopkinton. In case of cloudy weather, cooperative stations have been established at Toronto, Saskatoom, Birmingham, and Fort Worth.

The observers will use 14 spectrographs and ten direct cameras to record the appearance of the meteors. In order to photograph their spectra, special red plates will be used.

In addition to getting the spectra of the meteors, the watchers hope to find the velocity of the train drifts in the upper atmosphere, 60 miles above the earth. At this height there is a terrific speed and nothing else gives as good an idea of the velocity as the paths of the meteors.
