The 5 transits were made all the better by two huge festoons. They were so prominent and close together that at first I thought I was seeing the Great Red Spot but then realized they were too far north. But my most memorable part occurred 3 or maybe 4 minutes before the third shadow was about to make its appearance and a huge band of thick clouds just appeared from out of no where and spoiled the view. It was so bad that we actually stared stowing the refractor. We had it in its stowed position and had the dust covers on and the eyepieces removed when I happened to walk outside and look up to see that the cloud bank had vanished and the sky was clear! Those still closing the scope in the refractor bay were surprised when I ran back in exclaiming and pointing at the sky (which they could not see since the interior white lights had been brought up). We got the scope back on line and Jupiter back in view just as the final shadow moved onto Jupiter's cloud tops. Fun experience! Patrick
