Of course the big problem with photos is that there is WAAAAAY too much detail there compared with a visual observation. We could just be "up in the night" (pun intended) with this, you know, somebody makes a suggestion, e.g., "did you notice that bright star just below the nucleus before? No, I didn't!", etc. So what other options are there Patrick? --- Joe Bauman <bau@desnews.com> wrote:

Nova M31 2006 6 was reported in M31 back in early July, but it's too faint to be your baby. It's like mag 18: http://www.rochesterastronomy.org/sn2006/novae.html http://www.astronomerstelegram.org/?read=844 http://www.astronomerstelegram.org/?read=850 There is a discovery report of a new nova in M32 on 7/27/2006, but again, it's mag 17.2. M32 is "below" or "south" of the nucleus of M31. Can't say it is "west" though. See Nova M32 2006 at http://www.rochesterastronomy.org/sn2006/novae.html Discovery image http://www.rochesterastronomy.org/sn2006/nm3201n1.jpg As far as I know, there are no currently active supernova in M31.

Hi All, I can't get my Tinker Toy computer to hook onto the NASA television. But most of you probably can do it. Anyway, if you're interested, today there's a space walk at the International Space Station to connect a gizmo built by USU. Here's a story I wrote about it, which ran in Tuesday's Deseret News: Deseret Morning News, Tuesday, August 01, 2006 USU tool will help protect astronauts By Joe Bauman Deseret Morning News It looks like a metallic cross and researchers joke that its purpose is to ward off space vampires. Actually, the Utah State University-built instrument to be installed Thursday on the outside of the International Space Station will play a role in protecting astronauts from a dangerous invisible force: static electricity. The Floating Potential Measurement Unit, designed and built by USU's Space Dynamics Laboratory, will gauge electrical charges that build up on the outside of the orbiting station. It will also measure the space environment to help scientists better understand how the charges accumulate. This isn't ordinary static cling that makes your socks crackle nastily when you take them out of the drier. It's a potentially deadly jolt. If astronauts working in space were to touch the station where a big charge had built up, electrical arcing might hit the metal rings around their spacesuits' necks and wrists. "They might have currents passing through the space suit," said Charles Swenson, USU professor of electrical and computer engineering and the principal investigator for the project. Such a current, he added, "might damage the spacesuit or might damage the astronaut." Another concern is that arcing on the station's surface could hurt the anodized layer that serves as thermal protection. NASA officials wanted an instrument that would show whether the space station's electrical discharge equipment is working properly, and that would help them understand the physics of any electrical buildup. They commissioned Swenson and his crew at the Space Dynamics Lab to design and build such a device, in a $2.5 million contract. The outcome: the cross-shaped Floating Potential Measurement Unit. According to USU, within two years the lab developed, tested and delivered four of the units and a ground station. Finished three years ago, the unit's installation on the station was delayed because of the Columbia disaster that grounded the remaining space shuttle fleet for many months. The unit was stored in a bag filled with protective nitrogen, then finally launched aboard Space Shuttle Discovery on July 4. On Thursday it is to be mounted on the station's exterior, attached to a bracket originally intended to hold a camera. "Flight engineers Jeff Williams and Thomas Reiter continue preparations for Thursday morning's space walk," says a NASA Web site. The walk is to begin at 7:55 a.m. MDT. "Their main job is to install a device that measures electrical charging around the truss structure and solar arrays. After completing other duties, they should wrap up their space walk at 4:15 p.m. (2:15 p.m. MST). Commander Pavel Vinogradov will assist his two crewmates from inside the International Space Station." Swenson, whose research area is instrumentation for space science, said he is excited that the equipment will be installed at last. "There's a lot of interesting data that should come off this instrument," he said. "I imagine we'll be looking at data sometime within the next few days." Around 30 people were involved in the project at the Space Dynamics Laboratory, he estimated. The device is a cross with sensors at the ends of the arms, about 4 feet across and 4 or 5 feet tall. "The little arms fold down and it all folds into a nice package." During the space walk, Williams and Reiter will pull off the instrument's covers and lock the arms into place, then install it on the outside of the International Space Station. As components are added to the station, the electrical charging problem could become more severe. Its root cause is that, contrary to the name, the station really doesn't fly through airless space; it's orbiting in the ionosphere, the wispy outer edges of the atmosphere. The ionosphere is a thin gas that begins about 60 or 70 miles above Earth and extends 10 times that distance, he said. The gas molecules absorb sunlight and in the process electrons are knocked free. The ionosphere contains regular gas, ions and electrons. "The space station is flying through this charged gas and these charges build up on the surface of the International Space Station," he said. The connections between the station's solar cells collect charges. Eventually, the station itself could become charged. NASA engineers built in devices called plasma contactors to bleed off the charges. Swenson said agency officials "basically came to us and said we have concern whether that equipment is working correctly." ------------------------------------------------------------------------ E-mail: bau@desnews.com
