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:

  Jupiter Saturn
opposition August 14 March 9
conjunction with the Sun January 24 September 18
transit of the Sun in the equatorial plane of the planet (equinox) June 22 August 12
transit of the Earth in the equatorial plane of the planet (disappearance of the rings) April 15 September 4
Declination of the planets -20 to -13 deg. 0 to 8 deg.

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.
