That's it for the close-encounter downlink. Now we have to be a little patient and wait for the real data stream, which begins in about a week and will last through April. There will be lots more Tvashtar plume pictures, because it's near the north pole and so big that it rises above the pole itself, so every Io image we take will have that plume in it! We'll have color data and maybe even infrared pictures too, though detecting the plume in the infrared will be tough. The flyby is over, but the fun is just beginning.

In the meantime, there are a few black-and-white images to look at on the New Horizon’s image page, here, including this one of three volcanic eruptions on Io (featuring the immense plume that Spencer was so excited about above):
