Observations of the
occultation of January 25, 1975, are reviewed. The potential importance of
numerous visual observations near the occultation track and astrometric
observations with long-focus refractors near the time of occultation is stressed.
The vicissitudes of the occultation predictions prepared by Marsden and by
Herget indicate that accurate occultation predictions are difficult. Additional
unreported observations, positive or negative, from sites near the shadow
trajectory are earnestly solicited. They may be communicated to AAVSO
