Mercury stations retrograde on June 23, 1954 at 18° Cancer, and direct on July 17 at 9° Cancer — 24 days. From the Earth, Mercury seems to back up against the stars as we overtake it, as a car passed on the highway seems to slide backward. Astrology holds it a time for crossed wires and delays. Computed from JPL's approximate orbits; the stations agree with an almanac's to within minutes.
