Hello, We are preparing a webcast in the evening of march 5th for a 100 hours of Astronomy event. Among other activities, I´d like to have a partnership with...
... Although a new MPEC ( 2009 E10) has been issued with observations from I77, as of 0440UT the new orbit hasn't reached the Ephemeris generator. wait until...
The uncertainties for 2009 DD45 are now around 2' during closest approach. Additional astrometry (with the time accuracy now dominating the error) would be...

For those MPMLers curious as to what Rob McNaught and Gordon Garradd look like, there is a photo of them on the Sky & Telescope page discussing today's flyby...
A possibly heretical question. I am currently recording this asteroid via low-light video camera. Advantage is that I am time-stamping each video frame with a...
Hi Dave, Steve Quirk and I have done this with a Mintron and KIWI time stamp. He got his observatory code from such obs. Give me a call. Cheers, Rob ...

Given that the Epoch is 2008 Nov 30, perhaps your program isn't accounting for perturbations? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Robert H....

Hi Clay, Sorry, I'm afraid my software has misled you a bit here. It's doing a two-body solution (i.e., the effects of the earth's gravity between the epoch,...
For those that are interested - I solved the problem of getting a measurable image from the video as follows: 1. I displayed the video on a frame-by frame...
... Or, of more interest to me, photometric reduction. This little guy ought to be a super-fast rotator, maybe tumbling. If you have a long time sequence on...
I use video routinely for asteroid occultations - and we have excellent software for extracting a light curve from a video recording. I did measure some...
Dear all, you probably noticed that NEODyS at http://newton.dm.unipi.it is still unstable. We just want to let you know that we are working on it and we ...
Congrats on the captures. You all are good. I will post some links on my Black Sun blog Dr. Eric Flescher (kcstarguy@...), Olathe, KS:Â Lat 38.834, Lon...

It's been slow here so I hope y'all wont mind this off topic post. I came across a couple of slides I took years ago when I was first dabbling in...
For information. Our interest in asteroids might be seen by many as being rather arcane/esoteric/of not much general interest. With that background, I thought...
Patrick, Sorry if this is a duplicate post, but my reply from earlier this morning has never shown up on the list. The globular cluster is M13, but the reason...

Yes, Dave a great respnse, and great video too Congratulations, Juan A. Henríquez http://atlante.org.es 2009/3/4 Dave Herald <drherald@...> ... ...
Hello, We made a web cast of Lulin last week. The special web cast of comet Lulin from Israel, was a great success. Overall we had more than 38,000 entries...
Right you are Dennis. Flipping the image helped. More help came from taking the slide apart and cleaning the glass and the film. When I did that many of the ...
I'd like to photograph my meteorite collection with a 1-cm scale cube next to my samples, but I've only found two for sale on eBay, one of brass the other of...
I should mention that I've already thought about gaming dice and have gotten a few private emails about them too. Unless you can find ones that are exactly...
Dave, your video is very nice! An easiest way to obtain images from your video file, especially if you need a sequence of images to process them, is to use...
For those trying for this very fast mover now, currently the MPC MPES ephemeris is more than 1 degree off - the elements are already taking account of...
