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:
|conjunction with the Sun
|transit of the Sun in the equatorial plane
of the planet (equinox)
|transit of the Earth in the equatorial
plane of the planet (disappearance of the rings)
|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.

The observations made
The reduction of the observations has been made thanks to the FP7 ESPaCE program.
