Jupiter Impact, 10 September 2012

Post by Christopher K. » September 11th, 2012, 6:01 pm

Another smash on Jupiter has happened, taking place yesterday morning at ~6:35am CDT.

Dan Petersen of Racine, Wisconsin posted online that he had witnessed a bright white two second long explosion just inside Jupiter's eastern limb in the North Equatorial Belt. He was using a Meade 12" LX 200 GPS telescope and a binoviewer with 400x magnification. Then Dallas astrophotographer George Hall confirmed he had actually recorded the event; he was also using a 12" LX 200 GPS scope, with a Grey Flea 3 camera.

Though the flash is long gone, with the right equipment and cooperative skies there's a good chance one can see the "scar" marks. Below are the predicted times, generated by Sky & Telescope, for viewing the impact site. I've adapted them for Baton Rouge viewers using the same guidelines I use for the Great Red Spot. Jupiter is in Taurus.
13 September = 4:29am to 5:59am
14 September = 12:46am to 1:40am
15 September = 5:42am to 6:24am

Good luck site hunting!

Is it safe to intuit from your post that there won't be a time to observe it tonight (or rather, early tomorrow morning)?

I'm game for early Thursday morning if anyone wants to give it a shot. Perhaps we could image it in the 20"?

You're right about tomorrow morning. There are two possible times to see the impact site then. During the first Jupiter is too low and during the second the Sun is up.

As many have probably heard by now, there is sadly no appreciable visual aftermath following Monday's impact.

These incidents--both big and small--seem to be happening periodically over the last few years. I don't know whether they are related to some sort of meteoroid/asteroid stream (though the large ones may be comet pieces), or if there is currently a good vigilant group of amateurs worldwide catching basically random occurrences. I suppose if it were the former, there would be some preliminary data to show a pattern.
