Last night I managed to get away from the craziness of my family (at least for 20 minutes) and observe the transit of Io across Jupiter. It was quite a sight. Again, seeing conditions were very nice (4/5). The Great Red Spot was dead center, and I could clearly see both Io left of the planet (really, it was right of the planet due to my scope flipping the image) and its well-defined black shadow on Jupiter's surface. The CalSky representation below is a very accurate depiction of what it looked like.
