PHEMU 2015 campaign of the Mutual Phenomena of the Satellites of Jupiter (Aug. 2014 - Aug. 2015)
Next good event: 20th of December 2014
Next following good events: 21st, 22nd and 24th of Dec 2014
Starting in fall this year, the Jupiter system undergoes mutual eclipses and occultations of their satellites. Events which can be easily observed from central Europe will be announced here on this website, based on predictions by the IMCCE (France). The calculations are done for Munich, but can be used with minor changes of the local circumstances for most parts of Europe.

Announced are events with an intensity drop of more than 0.25 mag and Jupiter's altitude larger than 10 deg and the sun more than 5deg below horizon.

Next good next event is on the 20th from 5h 31min to 5h 51min UTC . Read more....

Occultations to Monitor Pluto's Atmosphere Before and During the New Horizons Flyby
The Pluto mission "New Horizons" is just a little more than 1 year away from its first destination, the Pluto system. In July next year the flyby will take place. Therefore the upcoming occultations of bright stars by Pluto are the last chance, to monitor Pluto's atmosphere in the time before the flyby. The next occultation is on the 5th of July 2014. Stellar Magnitude 15m7. Visible from southern Europe! Read more!
