Re: [Utah-astronomy] Jupiter Impact Transit Times for SLC
Patrick, My bad and you are correct. I am not a planetary observer as I stick 99% of my time with DSO's. What I saw was a shadow from one of Jupiter's moon as shown in this video http://www.youtube.com/watch? v=E7yZqLA4vXo. Having never observed a shadow transit I mistook it, and being tired . . . I didn't check the transit times on this (its even on a list of highlight events to watch that I get daily). So how does everyone like their egg from my face . . . scrambled or over easy? Guess I should have cut class tonight and gone to the SLAS general meeting . . . Oh well, I wondered why the spot was located in the center and not on the pole and I'm not the first to have done this as i saw this morning after reading your post Patrick that others on the night it occurred and the next night imaged shadow transits and posted their images thinking it was the scar. Interesting to me is on that form the discoverer Anthony Wesley goes by the name Bird, so this is being nicknamed the Bird Strike. In case you missed it here is CNN's interview with Anthony Wesley: http://edition.cnn.com/video/?/video/tech/2009/07/21/ bpr.jupiter.spot.astronomer.cnn I'll withdraw from the forum now and everything else and go back into the corner with my Dobs and DSO's, wipe the egg off. Clear skies to each of you! On 2009-07-22 09:59, Patrick Wiggins wrote:
Hi Jay!
Congratulations on seeing the spot. Well done.
But now I'm confused. If I'm reading Kurt's data correctly it does not show that a spot transit was to have been visible tonight (the 22nd UT).
What am I missing (other than missing seeing the spot tonight <g>)?

I am not currently in a position to be able to observe on work nights, but since I observed the SL-9 impacts back in '94 quite extensively, I can say that even the smaller impact sites were easily visible in a 10" Newtonian. If this impact scar is the approximate same size and has a similar contrast to the smaller SL-9 impacts, you should be able to see it in at least a 6" given halfway decent seeing. I still have video clips of the SL-9 impacts shot through my 10", but since they are on video tape, I have no idea how to capture them and transfer them to digital format.
Chuck, Do you still have the video camera? If so, you can play them in the camera and pipe the signal out to your computer via ports on the camera. Next you can make a digital movie using software available in stores. There's a program called Windows Movie Maker but I haven't tried it. There's also something called Roxio, which might work.

Thanks for the ideas, Joe. I have both Windows movie maker and Roxio. I've been experimenting with my hard-drive high-def camcorder for the past several months, but lack of free time has prevented me from making much progress. I just never have the hours needed to get substantive things done at the keyboard (or much else in the "elective" category, unfortunately). For the past ten years or so I haven't had "hobbies" so much as just "interests". *:o(* I'll see what I can do as time permits. Some of my video frames of SL-9 impacts were amazingly sharp.

I'd be excited to see them. When you get them digitized, why don't you post a few? --- On Wed, 7/22/09, Chuck Hards <chuck.hards@gmail.com> wrote: From: Chuck Hards <chuck.hards@gmail.com> Subject: Re: [Utah-astronomy] Jupiter Impact Transit Times for SLC To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Date: Wednesday, July 22, 2009, 8:28 PM Thanks for the ideas, Joe.

Don't feel too bad. A good friend of mine once reported an "exciting discovery" in one of his photos. The "discovery" turned out to be Uranus. :) However, having read your latest post and having looked at more images of the spot on the web, I've decided to skip SPOC tonight and concentrate on my regular duties.
