jupiter action
The night of the 2nd I was out in the back yard. Using the 12-inch I had some high power (553x) views of the lunar terminator -- far too many details to write about. At 10pm there was an Io transit of Jupiter, and Europa to come out of eclipse -- practically at the same time, 10:03pm. Jupiter was behind the meridian tree so I set-up my 8-inch and viewed at 295x. Seeing was pretty good. Io's disk punctured the limb and finally was a round bright disk over the NEB. Then I watched a small flare come into view following the planet -- and within about 30 seconds it, Europa, had become a bright disk. Io continued transiting and I could still make out its disk when 30 minutes later its shadow took a nibble from the limb. I watched until it was a complete circle, then packed it in for the night.
