I've been watching it all day. It's not as vivid now as earlier. I've been hoping for more but not seen anything yet. ------------------------------ On Mon, Feb 18, 2013 1:44 PM MST Dion Davidson wrote: >A coworker pointed out the solar halo visible today.

It animated well.on my Kindle while the first attempt didn't.

They're shooting at Chelyabinski
by jcarman6＠q.com 17 Feb '13

>From Wikipedia on fireballs The frequency of fireball sightings increases by about 10-30% during the weeks of vernal equinox . [ 33 ] Even meteorite falls are more common during the northern hemisphere's spring season. Although this phenomenon has been known for quite some time, the reason behind the anomaly is not fully understood by scientists. Some researchers attribute this to an intrinsic variation in the meteoroid population along Earth's orbit, with a peak in big fireball-producing debris around spring and early summer. Research is in progress for mapping the orbits of the meteors in order to gain a better understanding of the phenomenon. [ 34

2012 DA14 second attempt (photometry)
by Patrick Wiggins 17 Feb '13

17 Feb '13

Here's my second attempt at animating part of last night's 2012 DA14 pass: http://users.wirelessbeehive.com/~paw/temp/2012DA14-02.gif Like before it's an animated GIF so judging from what I heard last night some folks not using iOS are going to have problems playing it (I'm still looking for software to easily make animations that are cross platform). Details: 54 two second exposures taken between 0415 and 0433 UT on 2013 FEB 16. FOV is 18' x 26'. South is up, east to the right. Relatively bright star in the upper left corner is SAO 2554. Now, as for photometry, I've got 240 images taken between 0217 and 0433, spanning 3 fields of view. Given its speed and the 3 different fields of background stars I can't figure a way to get any worthwhile photometry. However, if anyone here would care to try I'd be happy to get them all the images. patrick
