Giant Jupiter is becoming lost in the glare of the Sun, as its current apparition approaches its end.
Jupiter’s opposition from the Sun occurred on 2018 MAY 08-09 with Jupiter in the sky all night. Apparent direct motion in right ascension resumed on 2018 JUL 10. Eastern quadrature (90° from Sun) was reached on AUG 06 before conjunction behind the Sun on NOV 26.

* A meridian transit occurs when a celestial body crosses an observer’s local north-south line in the sky. That is practically simultaneous with culmination, i.e. the highest altitude for the day. The Jupiter meridian transit times in the above linked graph can be easily transformed for your location. The given times are nearly the same for the central meridians of all time zones, i.e. those evenly divisible by 15° such as 75°, 90°, 105° or 120°. Do not adjust to UT. Simply add to the chart time 4 minutes for each degree west of a central meridian, or subtract 4 minutes for each degree to the east. If on daylight savings time, add an hour.
