Mutual occultations of the satellites of Jupiter in 2014

All instants are given in UT.

1o2 means that satellite I occults satellite II, etc.

"Start" is the instant of first exterior contact, or the beginning of the occultation. "End" is the instant of last contact. These times are given in hours, minutes and seconds.

Column "Magn." gives the magnitude of the occultation in %, that is, the fraction of the diameter of the second satellite that is occulted by the first satellite at maximum phase. 'T' means that the satellite is totally occulted, while 'A' means an annular occultation; in the latter case, the first satellite is projected entirely on the second satellite.

Column "Dur." gives the duration of the total or annular phase, in seconds.

IMPORTANT : Not all these events are visible from a given place!

Notes

Satellite II itself is eclipsed in Jupiter's shadow.
During the occultation there are two conjunctions between the centres of the two satellites.
The occultation reaches a first maximum (54%) at 23:44, then a minimum (10%) at 00:46, and a second maximum (82%) at 01:51 when II passes almost entirely in front of I.
Satellite II leaves satellite I from the same side as that when the occultation started.
Between these two events, the two satellites remain close to each other. The angular separation between the centres reaches a maximum of only 1.7 arcseconds, at 20:12.
The occultation begins when both satellites are in transit over Jupiter. Transit-Emersion of both I and II occurs at 22:25.
Both satellites are in transit over Jupiter.
