For tonight's SPOC Party - Comet 9P/Temple coordinates
Patrick, if you are using the 30" tonight, here's the position of Comet 9P for this evening from the JPL generator. Its brightness is mag 9.3 - Time RA Dec 08:00 PM 13 04 34.30 -00 29 28.6 09:00 PM 13 04 36.72 -00 30 25.4 10:00 PM 13 04 39.14 -00 31 22.2 11:00 PM 13 04 41.58 -00 32 19.0 12:00 AM 13 04 44.03 -00 33 15.8 - Canopus56 (Kurt) __________________________________ Discover Yahoo!

Many thanks. We'll check it out. Will be interesting to see if it brightens enough to notice after its encounter with Deep Impact. Patrick Canopus56 wrote:

Patrick, I believe you had mentioned at a SLAS meeting that in a Solar System Ambassador briefing, NASA said that the impact would not be visible from Utah. Checking the JPL Ephemeris Generator, if the impact occurs as advertised at 6:00 UTC on July 4 (the evening of July 3 at midnight), Comet 9P will be very low to the horizon (18 deg. alt) with much extinction - Date_time RA Dec Az Alt 2005-Jul-04 05:00 133747.08 -093301.6 226.4 27.1 2005-Jul-04 05:10 133747.81 -093311.5 228.7 25.7 2005-Jul-04 05:20 133748.55 -093321.3 230.9 24.2 2005-Jul-04 05:30 133749.29 -093331.1 233.1 22.7 2005-Jul-04 05:40 133750.03 -093340.9 235.1 21.2 2005-Jul-04 05:50 133750.78 -093350.7 237.2 19.6 2005-Jul-04 06:00 133751.52 -093400.5 239.1 18.0 2005-Jul-04 06:10 133752.26 -093410.3 241.1 16.3 2005-Jul-04 06:20 133753.01 -093420.1 242.9 14.7 2005-Jul-04 06:30 133753.75 -093429.9 244.8 13.0 2005-Jul-04 06:40 133754.50 -093439.7 246.6 11.2 2005-Jul-04 06:50 133755.25 -093449.5 248.4 09.5 2005-Jul-04 07:00 133755.99 -093459.3 250.1 07.7 Not much to work with, but still worth a look-see. An hour's delay would make all the difference. I don't believe this ephemeris includes the one-way light travel time delay. - Canopus56 (Kurt) P.S. - Can you use your _pull_ with NASA to get them to go at 5:00 UTC instead of 6:00 UTC? -:) --- Patrick Wiggins <paw@trilobyte.net> wrote:

Hi, "...not be visible...", in this case, means that while it'll be above the horizon, being so low in the sky, so faint and diffuse I'd be very surprised if the casual observer will be able to pick it out (we had trouble seeing it the other night with the Big Scope). Then again, maybe after the impact it will brighten so impressively that it might be visible after all (but I'm not holding my breath). Rob in Maui will have about the best land based seat available. It will be interesting to see if he sees anything. Patrick
Hi Patrick I'm involved w/ the NASA Outreach Program and have opted to be at our local community college where we'll have a near real time link to the 2 meter Faulkes scope here on Haleakala and a web link to a scope on Mauna Kea. We'll also be video linked w/ students in Iceland and the UK that have been involved in this project. We'll also have some astronomers from IfA along as well as several scopes set up so the public can actually see the comet as it actually is. Our biggest challenge is to get the campus lighting shut down by the Ka Lama building and around the area where the scopes are located. Not knowing how the impact will pan out, I'm guessing w/ a big scope we have a better chance of seeing the event than hoping to see an outcome. Either way, it will be good to provide some of Maui's citizens with an exciting view to an exciting project. A hui ho Rob
Neat stuff. Please post the appropriate URLs when you have them so those of us stuck on the mainland can watch over your shoulder. I just hope the media doesn't hype this too much. I'm already seeing reports of "dramatic" brightening being forecast after the impact. Those of us here on Utah Astronomy know that a 2 or 3 magnitude brightening from 9 to 7 or 6 is going to be readily apparent in CCD images but I fear the public will be expecting a much brighter display. That, of course, will lead to more references to astronomers not knowing what they're talking about. Patrick Rob Ratkowski wrote:
