2009: equinoxe on Jupiter et Saturn
THE CAMPAIGN OF OBSERVATIONS PHEMU09 OF THE MUTUAL PHENOMENA OF THE SATELLITES OF JUPITER AND SATURN IN 2008-2010

A mutual occultation: the photometric signal

Important facts and dates in 2009:

In 2008-2010, a series of eclipses and occultations will occur among the satellites of Jupiter and Saturn thanks to the equinox on these planets occurring in 2009. The observation of these events provides valuable data and is possible even with a small telescope. However, in order to be scientifically useful, the observations must be performed very carefully following very precise instructions.

The following notes provide more information.
