Galilean Satellites Phenomena

The data for this page come from the French Bureau des Longitudes.
Phenomena of the Galilean satellites of Jupiter.
Phénomènes des satellites galiléens de Jupiter.
Despite similar titles, the two pages have complementary as well as overlapping content.

Galileo used numbers to identify the satellites: I, II, III, IV, in order of inreasing distance from Jupiter. The names were adopted only in 1847, from a 1614 suggestion by Simon Marius.

Number	Name
I	Io
II	Europa
III	Ganymede
IV	Callisto

Predicted times for the Galilean satellites eclipses (EC) and occultations (OC), transits in front of Jupiter (TR) and transits of their shadows (SH).

The tables use Terrestrial Time (TT). This differs from Universal Time Coordinated (UTC) by 64 seconds (approx.). Here are the rules to convert TT time to local time in NJ. First, subtract 64s from TT to get UTC. In winter NJ local time is Eastern Standard Time (EST), subtract 5 hours to convert UTC to EST. In summer NJ local time is Eastsern Daylight saving Time (EDT), subtract 4 hours from UTC to get EDT. Converting TT to UTC.
