Easily visible this morning in 12x25mm binocular. The nova forms the head of a little kite-shaped asterism, oriented roughly north-south. Still not visible to the unaided eye, but there was more high cloud this morning than yesterday. It should be visible from a rural location- Kim, have you taken a peek yet? I am not getting my own posts at all anymore. I'm going to check my mail settings on the list tools page and see if something got changed inadvertantly. ____________________________________________________________________________________ We won't tell.

Thanks, Joe. Novae used to be discovered by "blinking". Two photographs of the same region would be taken, days, weeks, or months apart, and the researcher would compare the two by looking at each in rapid succession on a device called a "blink comparator". Any star seen on one but not the earlier photograph would appear to blink on-and-off. It would be an easy, straightforward project to do the same thing on the computer, with digital images. Amateurs can easily discover novae, even today. One popular low-tech approach from another decade was the projection comparator. Two identical slide projectors with a motorized, rotating shutter in front of the lenses, so that only one slide at a time was projected. This was the "astronomy club" method. Also easier on the eyes than staring into a bino or mono viewer for extended periods of time. I'm still not getting my own posts so thanks for letting me know that it came through, Joe. --- Joe Bauman <bau@desnews.com> wrote:

Hi Joe, To see all of the posts list has received and rebroadcast go to: http://mailman.xmission.com/lurker/list/utah-astronomy.en.html pw
Patrick, these do look familiar. I guess I have been getting all the posts. I just expected more. Maybe crankiness by some of us (i.e., me in a past debate) caused comments to dry up. If so, I apologize and beg former contributors to get back into it. Thanks, Joe

Egads, I hope no one feels they need to apologize for stuff that has been posted here. Not only have posts here been just part of an exchange of ideas amongst (mostly) friends, the stuff I've seen here is downright tame compared to the flame wars and personal insults I see getting splattered around some of the other groups I'm subscribed to. pw
. If so, I apologize and beg former contributors to get back into it. Thanks, Joe Nah Joe. I've been out of town for most of the last couple of weeks. So I haven't been able to rile anybody up.

OK, Rich provided the clue. It turns out that, randomly, a few weeks ago, some posts from utah-astronomy started going into my bulk folder (spam), where I have directed that they be deleted on receipt. I have no idea why some (including my own) go to "bulk", while others get through to the "In" folder. The same sender will get randomly sorted first to one folder, then the other. It appears that the problem is with Yahoo, in my case at least, and the criteria they use to distinguish spam. I have now changed the "kill on receipt" setting and will have to weed through the spam to get the astro-list postings, but it appears that I at least will get them. Others with a similar problem may want to investigate the same possibility. ____________________________________________________________________________________ Finding fabulous fares is fun.

The delay is pretty normal on many (most?) of the lists I'm on. Off the subject but here's a video of the ultimate private jet. :) http://jet-man.com/playervideo.swf?video=jetman2007.flv pw
I have on occasion had the same thing happen. I'm not sure how Yahoo's spam filter works (of course they don't really want people to know the specifics or the spammers would use that info to get around the filter) but I do think it tends to be particularly suspicious of mail that comes from a different IP address than what is listed as the return address. Of course the Utah-astronomy list postings fall into that category. It does however, seem to be fairly teachable, so identifying mail in the bulk folder as "Not Spam" helps to keep it from going there next time. In my case anyway, it seems to be worthwhile turning off the immediate delete and checking the folder once in a while. There occasionally is other stuff that shows up there that I would like to see. --- Chuck Hards <chuckhards@yahoo.com> wrote:

Chuck, Do you have filters set up on your Yahoo mail? That way you can automatically sort the Utah Astro messages to your inbox (or another folder) and make sure they don't land in the Bulk folder. Scott --- Chuck Hards <chuckhards@yahoo.com> wrote:

Thanks, Scott- excellent idea. I've now configured my filter to send all list postings to their own folder (hopefully, unless some clever spammer starts using the utah-astronomy name in the "from" row). That solves the problem of sorting through the spam, now I only need to find out why many posts aren't getting to me at all, in any folder. --- Scott Catron <zaui@yahoo.com> wrote:

Anyone remember the Problicom program run by Ben Mayer in LA? There are at least a couple of us here on UA that participated in that program back in the 70s, 80s and early 90s. As Chuck mentions we'd take pictures of the same areas of the sky once a month and then "blink" them using two slide projectors and an occulting disk. Taking the pictures was easy but scanning them was a real pain as one could never get the images to line up exactly so the images were always jumping back and forth or up and down. And the many variable stars and "Kodak novae" (tiny defects in the images that looked like stars) did not help either. It's soooo much easier today. Just shoot a couple of digital images, stick them in a program like CCDSoft and the software aligns them precisely, blinks them and even highlights any possible novae.

People used too-short lenses. Longer f.l. lenses would have allowed a much better alignment. But most folks just used the lens that came with the projector, and never purchased a different one. --- Patrick Wiggins <paw@wirelessbeehive.com> wrote:

The press calling the second new nova (is "new nova" redundant?) in Scorpius "naked eye" is being very generous. It may brighten enough to be seen with the unaided eye, but it's still dimmer than 8th, last time I checked-up on it. The first nova has already started dimming and is past it's peak. ____________________________________________________________________________________ Any questions?

Chuck: I've also been missing alerts and postings, so I knew nothing of the nova until I read your post. High, thin clouds this AM would have made observations less than ideal, anyway, so I'll try to look tomorrow. Nice view of the crescent Moon as it rose over the Wasatch Plateau awhile ago. I probably wouldn't have noticed it but I was watching a lone bald eagle as it (playfully?) tucked its wings for a steep dive toward the ground, then spread them wide to soar upwards again, not unlike a roller coaster. Fascinating to watch. Anyway, it soared right above the horizon and brought my attention to the rising Moon.
