GRAZPREP-software: Find and prepare Grazing Occultations in detail
Grazing Occultations of stars by the moon are local events and thus require an individual selection according to personal observation preferences. The GRAZPREP-software assists in all aspects of finding individually interesting events as well as selecting the best observing stations promising the most contacts between the star and the lunar limb in high resolution. GRAZPREP can be downloaded and installed, including a step by step operation tutorial. Go to the Members login part of the website!
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!
