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

Important facts and dates in 2014-2015:

  Jupiter
opposition February 6, 2015
conjunction with Sun Jul. 2014 & Aug. 2015
transit of the Sun in the equatorial plane of the planet (equinox) February 5, 2015
transit of the Earth in the equatorial plane of the planet 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.
