2015: equinoxe on Jupiter
THE CAMPAIGN OF OBSERVATIONS PHEMU15 OF THE MUTUAL PHENOMENA OF THE SATELLITES OF JUPITER (Aug. 2014 - Aug. 2015)
A mutual occultation: the photometric signal

|transit of the Sun in the equatorial plane
of the planet (equinox)
||February 5, 2015
|transit of the Earth in the equatorial

||Nov. 8 2014, April 10 and May 5, 2015
|Declination of the planet
||+22 to +20 deg.
In 2014-2015, a series of eclipses and occultations will occur
among the satellites of Jupiter thanks to the equinox on this
planet occurring in 2015. 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 technical notes PHEMU provide more information.
