At last night's SLAS meeting we watched an animation of two galaxies colliding, resulting in a "tadpole" asterism. It looked like the animation was of Caldwell 60 and 61 (Arp 244) - Arp244 NGC 4038-4039 C60-61 J120152.48-185202.9 mag 10.3-10.5 Unfortunately C60-61 is between Corvus and Carter and is below the horizon. Checking Arp's Atlas of Peculiar Galaxies - << http://nedwww.ipac.caltech.edu/level5/Arp/frames.html
for similar galaxies that are currently visible, Arp's numbers 233-256 concerns galaxies with the appearance of fission. For you light-bucket faint-fuzzy searchers, a few Arp galaxies that are above the horizon (albeit off-zenith in the west) and that are similar to the animation we viewed are: Arp240 NGC5257 http://nedwww.ipac.caltech.edu/level5/Arp/Figures/big_arp240.gif J133952.94+005024.4 mag V12.9 dia. 1.8' Arp238 UGC8335 http://nedwww.ipac.caltech.edu/level5/Arp/Figures/big_arp238.gif J131500.00+620600.0 mag 15 dia. 0.85' Arp241 UGC9425 http://nedwww.ipac.caltech.edu/level5/Arp/Figures/big_arp241.gif J143751.13+302847.0 mag B15 dia. 0.85' Arp242 NGC 4676 (The Mice Galaxies) http://nedwww.ipac.caltech.edu/level5/Arp/Figures/big_arp242.gif J124610.18+30 43 53.7 mag B14.1 dia. 1.37' I haven't personally observed these, so I can't express an opinion on the practicality of seeing them under current conditions. - Enjoy Canopus56(Kurt) __________________________________________________ Do You Yahoo!?

We had a visitor last night and could not attend the meeting. Could someone send a brief description of the talk and tell about the talker, just for my future reference? Thanks, Joe
You missed it! We had a very remarkable and talented young lady tell us how to escape from a black hole. For those who like to stretch a dollar, the event threshold would be the place for you. Of course, getting chopped and chewed and pulled to pieces going through a black hole while holding onto the dollar wouldn't be too cool. Once in the black hole, I don't think I would have the energy or desire to escape... ;) Thanks Ann. Good job! Quoting Joe Bauman <bau@desnews.com>:

Yo, Rob... well uhhhh what are you waiting for?? And Chuck, I would like you here too !! have fun,Aloha Rob
Anyway, you are still welcomed here in Hawaii anytime you or any other SLAS member may venture this way. It's a great place, good clear clean air and when it's nice IT'S REALLY NICE !! Aloha from Maui Rob
Maui is awesome. We were there 3 years ago for a week or so and loved every minute of it. How wonderful that you actually get to live there.

Guy, I did some Lunar observing while night diving in a fresh water lake. My friend and I were on the surface and turned off our lanterns. It was near full moon. We turned on our backs and bled our BCs and slowly sunk to 40 feet at which point our tanks clunked on the rocks. The whole way down we watched the moon shimmer on the surface of the lake. Quite a peaceful astro/scuba moment even if it was at 1X... B) 73 de n7zi Gary "Why buy something for ten bucks when you can make it for a hundred."

I was diving in a field of ice at a depth of 27 degrees Farenheit. Just moments before an unscheduled, uncontrolled dash to the surface because of a free flowing regulator and dry suit inflator valve, I had been watching my exhaust bubbles. At that temperature, the air bubbles would freeze and glaze over, and as the bubbles grew in size, they would break into a gazillion shimmering shards of ice crystals, only to reform and repeat the process. The larger shards of ice held the image of the sun, which was overhead. That was one of the coolest things I've ever seen. Of course, hitting the surface like a runaway polaris missle wasn't very cool at all... :( Doing surface intervals while floating under a star lit sky, rule! Quoting Gary Liptrot <n7zi@comcast.net>:

Not too far below the surface of a calm freshwater lake, the view can sometimes resemble what you see when looking through a fish eye lens. Under Ideal conditions, you can see incredible wide angle detail. I would like to see the Milky Way under those conditions just for laughs. I will be going to Fish Lake around the first of September to dive and view the stars. The sky over Fish Lake is as dark as I've ever seen it. Maybe there is others here who would like to go if for nothing else than to see another cool dark sky site, with maybe a little fishing or diving. Quoting Josephine Grahn <bsi@xmission.com>:

I remember reading an article in either Astronomy or Sky & Telescope a few years ago about someone who observed the milkyway while submerged in their swimming pool, they also described it as looking through a large fish eye lens, sure would be a surreal experience to lay underwater looking at the stars, I look forward to the report from Fish lake.

That's rather faint, and at the listed size I'm thinking it might be pretty indistinct. Do you think you could discern any structure at SPOC? I wonder if a broadband LPR might help. (yes I know they are not optimized for stellar sources) What's the policy on using one's personal eyepieces on the Grim scope? Did Bruce adjust the spacing for a tad more "in" travel?

It's just a suggestion in follow-up to Tuesday's meeting that probably will not pan out. The only way to tell is to look. (I was also interested in making a short list of these interacting galaxies, so I don't miss them next season.) SPOC is LPR limited, but I'm not going to guess what the Grim Scope can reach. The two times Mark B. has demoed it for me into light polluted areas using an LPR filter, the 30" scope was doing more on extended objects than I would have ever imaged. My recollection of that particular RA and Dec is at 11:00pm it is in a mag 5.3 darker pocket NW of the Grantsville West-I15 horizon light spike. But I'm shooting for the hip - or keyboard -:).
Do you think you could discern any structure at SPOC?
Probably not, other than gross interacting disks. If not, I'll just have to wait for C60-61 to swing around next spring. - Canopus56(Kurt) --- Chuck Hards <chuckhards@yahoo.com> wrote:
