Hello, Since our model of 160 Una has been mentioned, we displayed it at the plane of sky for the epoch of the occultation (24 January 2011, 4:15 UT). At: ...
... Well, no, this is mostly "fluff" news -- true enough, but not news. It has been well known and understood that small irons make it through the atmosphere....

Dear Comet observers We have added a new Comet observing planner tool to the COBS website which is groving every day. A lot of new observers have joined and...
The conclusions of our paper, as John correctly interpreted, is that the number of iron/nickel meteoroids surviving intact after the interaction with the...
... Have you been following the news from Mars about meteoroid finds there (by the MERs) ? There have been a number, and they seem to be mostly nickel-iron....
Heyho list, I suggest to observe the upcoming flyby of asteroid 2001 OC70 at asteroid Amherstia for documentation purposes during the next hours if possible. ...
Mario, I certainly did not intend my remark to diminish the importance and the quality of your and your colleagues work on the Gebel Kamil crater and ...

Another way to see the image is to go to SkyMorph site and simply search for images associated to this position (no time specification is needed): RA:...
One suggestion - the position is a few (8?) arcminutes from a bright star (V=4.9, Sp=M0, V-I=1.75). What about artifacts produced by this star. Presume the...
The Asteroid Lightcurve Database (LCDB; Warner, Harris, and Pravec, 2009, Icarus 202, 134-146) consists of numerous tables. However, the one most commonly used...
Richard, You should now be able to enter values to 4 dp precision. The limit is still in the range 0.0 to 1.0. Clear Skies, Brian D. Warner Palmer Divide...
Hi Alessandro, I see nothing unusual (for 608) in this image triplet. There are lots of hot (or dead) pixels in the FPA, and when triplets are taken, they ...

Hello all, (900) Moriyama got some more positions, within about an arcsecond of prediction, reported at http://www.minorplanetcenter.net/mpec/K11/K11C14.html...
Hello all, <Groan> Dunno what's going on here... I got a report of MPES being off, got exactly the same result, and now... it's working. Maybe I was getting...
Of zero observational interest, but perhaps some celestial mechanics interest, is the fact that 2011 CQ1 will transit the sun shortly after its close approach....
Hi Andrew, At 0.3", that's awfully close to being detectable by a large aperture solar telescope. Perhaps someone should alert Big Bear Solar Observatory of...
Hi again, Actually, the angular size is quite a bit smaller than 0.3". Even at closest approach (~11850 km) assuming a 3-meter size, it will only subtend...
