| Schrã¶Ter’s Effect |
A discrepancy between the observed and predicted phase of Venus around the time of dichotomy half-phase. Eastern dichotomy evening apparitions, when Venus is waning is usually a few days early, and western dichotomy morning apparitions, when Venus is waxing a few days late. The cause is not known for certain, but it may simply be that the region of the terminator the division between night and day is less bright than the rest of the illuminated hemisphere of Venus. Johann Schröter 1745-1816 was the first to draw attention to the phenomenon in 1793.
