Occultation of Beta Scorpii by Jupiter on May 13, 1971
Abstract
PHOTOELECTRIC observations of the occultation of the star β Scorpii by Jupiter were carried out at our field station at Kavalur on the night of May 13-14, 1971, at the cassegrain focus of the 38 cm reflecting telescope. Our photometric record was made by photographing a CRO trace in order to record the true light emission curve during the immersion and emersion phases of the occultation. The record was calibrated by photographing seconds pulses from a quartz clock simultaneously. A thin glass plate behind the focal plane diaphragm allowed continuous visual monitoring of the Jovian limb and the occultation phenomenon.
