Every day, interesting events happen between Jupiter's satellites and the planet's disk or shadow. The first columns give
the date and mid-time of the event, in Universal Time (which is 4 hours ahead of Eastern Daylight Time). Next is the satellite
involved: I for Io, II Europa, III Ganymede, or IV Callisto. Next is the type of event: Oc for an occultation of the satellite behind
Jupiter's limb, Ec for an eclipse by Jupiter's shadow, Tr for a transit across the planet's face, or Sh for the satellite casting its
own shadow onto Jupiter. An occultation or eclipse begins when the satellite disappears (D) and ends when it reappears (R ).
A transit or shadow passage begins at ingress (I) and ends at egress (E ). Each event is gradual, taking up to several minutes.

The wavy lines represent Jupiter's four big satellites. The
central vertical band is Jupiter itself. Each gray or black
horizontal band is one day, from 0h (upper edge of band)
to 24h UT (GMT). UT dates are at left. Slide a paper's edge
down to your date and time, and read across to see the
satellites' positions east or west of Jupiter.
