Mercury starts the season off in the morning sky, reaching greatest western elongation on July 4, appearing low in the east shortly before dawn. After that date, it quickly retreats back into the Sunʼs glow by mid-month, swinging behind the Sun and reaching superior conjunction on August 1. It then moves to the evening sky, but this evening apparition is an unfavorable one, as the plane of the Solar System (or ecliptic) is at a shallow angle relative to the horizon. Thus, Mercury never gets very high above the horizon, even at greatest eastern elongation on September 13.
The thin, waning crescent Moon and Mercury are a challenging pair low in the east-northeast before sunrise on July 8, but when they meet up again on August 8, they are too close to the Sun to be seen. They might be possible to spot low in the west just after sunset on September 8.
