Asteroids
by jcarman6＠q.com 06 Mar '13

06 Mar '13

There is a fun little quiz about asteroids at the space.com website. Link follows http://www.space.com/20085-asteroid-buzzes-earth-this-weekend.html One of the questions is: What is a potentially hazardous asteroid? a. Any one that hits earth b. One that is 500 feet wide and comes within 4.65 million miles of earth c. One that is at least 1 mile wide and comes within 1 million miles of earth I got this wrong, the correct answer is b. Does anyone know why b is the correct answer?

More on Mars / Comet
by jcarman6＠q.com 06 Mar '13

Interesting? I'm with Seth. Imagine a couple of minus magnitude Jupiters against a black background filled with pinpoints of light (no giant white orb in any phase); a comet with an extensive tail; and a speed demon moon. What a photo opp! Hmmm, may prove to be problem. What exposure time not to over expose the planets, but pick up the extensive, much dimmer tail. Well, that's what bracketing is for. Ahhh, if only we really had that problem. Of course, no dust storm, this is, after all, ideal conditions, and, ultimately, all in the human mind .

OT: Stansbury water
by Chuck Hards 06 Mar '13

06 Mar '13

I noticed that water from the Stansbury conservancy district was judged to be the best tasting in the state at a recent competition! Bryce Canyon took second place. Stansbury water will now go on to the national competition. So next time you get a drink from the fountain at SPOC, savor the experience. I'm guessing it's all that mining arsenic that gives the water it's unique bouquet. ;-)

Saturday's Sun Party at the museum
by Chuck Hards 06 Mar '13

06 Mar '13

Per Joe's SLAS blast, the weather is looking iffy for Saturday, but as of now they are still calling for afternoon clearing. If it clears in time remains to be seen. Keep the L&O meeting in mind if you were originally headed to the sun party and it gets scrubbed. I'll be bringing my new RFT OTA as well as a Baader 3" Steeltrack focuser (what a monster!)

ISON tonight, 2013 MAR 06
by Patrick Wiggins 05 Mar '13

Maybe during next week's comet watch, once PanSTARS has set and it gets nice and dark we can try using the Grim to spot ISON. In the mean time, here's ISON tonight: http://users.wirelessbeehive.com/~paw/temp/C_2012_S1.2013MAR06.JPG patrick

Re: [Utah-astronomy] Moon parallax (and stereo) follow up
