Mutual Phenomena for 2009–2010 and 2014–2015

About every six years the Earth’s orbit crosses the orbital planes of the four Galilean satellites. This results in a significant number of observable occultations and eclipses involving these satellites. These phenomena are tabulated on pages F38-F39 of The Astronomical Almanac and are available below. These data were provided by Dr. Kaare Aksnes of the Institute for Theoretical Astrophysics in Oslo, Norway.
