An observed eclipse of theta 1Orionis A.
Abstract
Photoelectric ohservations with UBV filters were made of one descent into primary eclipse, and three runs at constant hrightness, for the recently discovered eclipsing variahle Os Ori A. They show a smaller amplitude of variation than visual estimates reported previously for the same eclipse, hut are quite similar to Lohsen's photoelectric ohservations. Key words: eclipsing h inary- light curve-Orion trapezium
