Hi all,
Do check out the Hubble Site that describes recent changes on the Jovian surface. WOuld be interesting to see them in telescopic observations.

Yup I observed a lot of changes in Jupiter. Last Tues night, I noticed the bands getting 'erased' off (they became zones) and festoons merging together within prob half an hour I guess! I could not believe it as though Jupiter features were moving so quickly! 
I also observed Europa and Europa's shadow transit. Also one of the white ovals (there were 2 of them ) that is near the Red Spot Junior has shifted very near to the Red Spot Junior. Perhaps they will merge...
Jupiter is very interesting to watch now.

I just checked out when was Jupiter's opposition this year. It was June 6th. Looks like I guessed correctly as the last time I observed Io's small shadow (half shadow) was on June 7th which was one day later than the opposition. Just so happened there was clear sky and I could see the transit and shadow transit of Io.
Opposition meaning that Jupiter, Earth and Sun are in line (Jupiter closest to Earth). Hence the sunlight will be reflected directly (face on) Jupiter, not at an angle.
Also from the orientation (on 7th June), Io crossed Jupiter followed by the small shadow ('attached to Io') which meant that opposition ended a day earlier. Few months back, at Tampines, with Weixing and a few other people, I observed the shadow of the moons first than the moon transit. If one observed Jupiter moons transiting exactly during opposition, I guess there will not be any shadow seen as the shadow will be behind the moons. After that opposition (currently), the moons will transit first then followed by their shadows. Which makes sense..else Jupiter will be moving the reverse direction! Note this is for a Newtonian (inverted) telescope view.
Cheers.
Anybody recently observed the changing cloud patterns , transits/shadow transits of the moons and GRS/Red Spot Junior on Jupiter?
