As the nights get shorter and the Earth spins along, Jupiter sinks toward the western horizon… soon to be engulfed in the murk and turbulence of the atmosphere close to the horizon, (which unfortunately is where saturn and mars currently lay :-()… having said that its been a great show on Jupiter this past few months and using my C11 SCT with bino viewers has given me some of the best views of the planet I have ever had…. but as they say all good things come to an end… until next year that is =D> .
Jupiter is still nice and high in the early evening so with a little luck and some good seeing we should get some good views on Saturday.
I will be there with bino viewers in hand…. there might even be a
C11 or two on site…. for sure there will be a C8 😎
See you Saturday… gate time to be announced… i should be there 9ish.
NOTE: Mars (on a close approach to Earth) and Saturn will be up there also.

At 8:18 PM PST on Friday, 6 May, one of Jupiter’s moons, Callisto, will pass in front of Jupiter. At 8:32 another Galilean moon, Io, will follow Callisto. Their two shadows will transit the planet’s surface starting at 9:39 PM. The double shadow transit will end at 10:42 PM PST. We’ll have the SCC Observatory open for this double shadow transit at 8 PM, weather permitting.
Did you know that a Solar Eclipse is not technically an eclipse but is an Occultation? An eclipse takes place when one body passed into the shadow of another as seen by an observer and an Occultation is when one passes in front of another…Lunar eclipse is correct because the moon passes through the earths shadow. So whats happening now is that Jupiter’s orbital plane is pointing directly at us so from our vantage point here on Earth we can observe Jupiter’s moons eclipse and occult each other. When one moon passes in front of the other we have an Occultation and when one moon passes into the shadow of another its an eclipse… The next visible event is this Sunday the 15th at 11:23 and again at 11:43 pm.

On the night of Friday January 23 at 9:48 PM PST a rare triple shadow transit will occur involving Jupiter’s moons Europa,Callisto, and Io. Observers will see the shadows of the moons on the surface of Jupiter and see them merge. We’re hoping that the skies will be clear enough on that day for a star party at the airport to view this event. We will be meeting people at the Sechelt airport gate at 7:30 PM on January 23 to convoy in to the observatory site to set up telescopes in an attempt to view this event (weather permitting).
Update 19 January: Looking at the weather forecast for Sechelt, things don’t look that hopeful for us Sunshine Coast Centre members hoping to view this transit. It is calling for rain from the 22nd to the 24th at present. We’ll keep an eye on it in case it changes. Stay tuned for updates to this post with times and details!
