(I imagine that timing their ocultation will be hard with my 10x50 binocular, but I would try)." [this time for the list] There is a great little Javascript calculator on skyandtelescope.com that displays the current positions of the moons and upcoming occultations and other events. It's very nice. Go here: http://skyandtelescope.com/observing/objects/planets/article_830_1.asp By the way, you need much higher magnification to see occultations. That me ans a long focal length telescope which is why the method was found to be impractical at sea. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
