Tuesday night anyone?
by Richard Tenney 04 Apr '05

According to this: http://www.wrh.noaa.gov/slc/forecast/textproduct.php?pil=zfp the only clear night we'll have this (new moon) week is tomorrow (Tuesday). I'm thinking of heading out to Rush Valley (Pit 'n Pole) if anyone's interested, and it's not too muddy out there after today's anticipated showers. I know it's a weeknight and all, I just hate to miss an opportunity in the Spring when the weather seems to always be against us (that, and the fact that the vast majority of the remaining ~130 objects left on my Herschel-400 list are galaxies in Virgo/Leo Minor/Ursa Major/Coma B./etc.). RSVP if you're up for it. -Rich __________________________________ Yahoo! Messenger Show us what our next emoticon should look like.

Tyler, you might also find interesting the following article about the 2000 discovery of an x-ray source embedded in IC443 by three high school students. http://www.msfc.nasa.gov/news/news/releases/2000/00-332.html http://www.msfc.nasa.gov/news/news/photos/2000/photos00-332.htm - Canopus56 __________________________________ Do you Yahoo!?

Nice image Tyler! Are you going to go back and get the RGB information or just leave it "as is"? There are lots of H-alpha targets in that area of the sky.

A few pictures
by Patrick Wiggins 03 Apr '05

03 Apr '05

Between chasing asteroids tonight I shot a few fun pictures. All with the C-14 @ f/5.5 and the ST-10 unguided. No special processing with only dark and flat frames applied. M-101 was a 6 minute exposure, M-51 was 3 minutes, M-63 6 minutes (no flat field) and M66/M-65 2 minutes. http://www.trilobyte.net/paw/temp/01APR2005.JPG Patrick

In a recent journal article, IC443 was described as "two half-shells" of hydrogren gas. The two half-shells are due to a "ring of shocked molecular gas that sits at the join of the half-shells." Part of the remnant is being blown away by a nearby, but unrelated pulsar. "The pulsar wind nebula found by Chandra likely originates in G189.6+3.3 rather than in IC 443." http://simbad.u-strasbg.fr/cgi-bin/cdsbib?2004AJ....127.2277L Your photo appears to nicely show the beginnings of dispersion of part of the remnant into the instellar medium (ISM). - Canopus56 __________________________________ Yahoo!

IC443 H-alpha Image
by Tyler Allred 02 Apr '05

Hi all. During our last clear night, I tried imaging IC443 with an Astronomik 15nm bandpass filter. This object is a supernova remnant with a suspected neutron star. The neutron star is perhaps only 20 kilometers in diameter, but has more mass than our sun! I was only able to get 4x10minute exposures before it went behind the trees in my back yard, but it is a good start. I am very interested in doing more H-a imaging, because it can be done when the moon is very bright. Use of this filter will allow many more opportunities for imaging without worrying about a bright moonlit sky. I hope someone enjoys the image. Here is a link to a thumbnail image.. click the thumbnail for a larger version: http://www.utahastronomy.com/album16/Utah_Astronomy_IC443_Ha_Lum Cheers, Tyler

Signing pictures

The governor's office has posted pictures of yesterday's Astronomy Week signing ceremony. http://governor.utah.gov/photos/Photos%20for%202005/March/March%2024/Declar… Is it me or does the Gov. look intimidated by Sieg? :-) Perhaps some of you clever types out there can come up with humorous captions for the pictures?

I'm going to be mostly away from the computer from now until April 19th... so, be nice, and take care. =) I'm going to go to no-mail on the list so when I'm gone my box doesn't fill up. If you need me, I'll be semi-around until April 8th, then I'll be in Moab until the 18th. =) I hope it's clear! Cyn
