Reappearance of an occultation of the Mars by the moon on 3rd January 1967 was observed at the Sirahama and Kurasiki Hydrographic Observatories by equipment for routine observation of ordinary occultations. Photoelectric device at Sirahama is calibrated against the UBV-system by observation of some field stars and Hyades members. The record of the Mars’ occultation is then converted into the luminosity ratio on B-magnitude. For prediction of occultation, the inclination of the moon’s limb to its mean level and the phase of the Mars are taken into account. Brightness of the Mars is assumed to be uniform all over its illuminated part of the disk. Several light curves of the Mars are thus drawn and are compared with the observation record. (0-C) in time of the reappearance of the centre of the Mars’ disk is 0~6 0~3 for Sirahama, if the Astronomical Ephemeris is used without any amendment.Journal
