                                               2014-2015 APPARITION OF JUPITER


The bright planet Jupiter now rises during the evening. Western quadrature (90° from Sun) was reached on NOV 14. Apparent retrograde motion commenced on DEC 09.


   Jupiter’s opposition from the Sun will occur on 2015 FEB 06 when it will be out all night. That will also be the date of its closest approach (4.3462 AU) and greatest brilliance (magnitude -2.6) for this synodic cycle. At that time its equatorial angular diameter will be 45.3 arcseconds, and its apparent axial tilt will be -0.2°. Jupiter will resume apparent direct motion on APR 08 and will reach eastern quadrature on MAY 04. Conjunction behind the Sun will occur on AUG 26.


   The orbital planes of the four great Galilean satellites are nearly coincident with Jupiter’s equatorial plane. During this apparition those planes nearly include the Earth and Sun, thus resulting in numerous mutual occultations, transits and shadowing events among those satellites not necessarily involving Jupiter.


   Jupiter will appear near other bright planets and stars on the following dates: Venus 2015 JUL 01, Mercury AUG 07 & Regulus AUG 11.


   The Moon will appear to pass near Jupiter on 2015 JAN 08, FEB 04, MAR 03, MAR 30, APR 26, MAY 24, JUN 20, JUL 18 & AUG 15.


NOTE:  Events in this article are geocentric in Universal Time unless otherwise noted.


*  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.
