                    2016-17 APPARITION OF JUPITER


Apparent retrograde motion in right ascension for Jupiter commenced on FEB 06. Opposition from the Sun occurred on 2017 APR 07 with Jupiter in the sky all night. At that time it was in the constellation Virgo at a declination of 5.7° south of the celestial equator. Its south pole was tilted by 3.8° toward Earth. The orbital planes of its four great Galilean satellites were similarly tilted. Greatest brilliance for this apparition was expected around that same date at stellar magnitude -2.5. Jupiter’s closest approach to Earth of 4.4549 AU occurred on APR 08 while subtending an equatorial angular diameter of 44.3 arcseconds.


   Apparent direct motion in right ascension will resume on 2017 JUN 09. Eastern quadrature will be reached on JUL 05 before conjunction behind the Sun on OCT 26.


   Jupiter will appear nearest to Spica on 2017 SEP 11.


   The Moon will appear near Jupiter on 2017 MAY 07, JUN 03, JUL 01, JUL 28, AUG 25, SEP 22. There will be no lunar occultations of Jupiter during this apparition.


NOTES: Event dates in this article are for North American Central Time. Galilean satellite positions are calculated utilizing the high accuracy algorithm of Jay H. Lieske.


*  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.
