My friend, Rick Johnson, in Minnesota, captured this video of the recent asteroid flyby that everyone was talking about. Here is his post from usenet:
After finding the MPC elements were too far off and the Horizon's site
pummeled into submission I finally got good elements about 3 hours after
closest approach. This is a 3 minute animation, 15 second frames,
tracking the asteroid. Taken with a 14" LX200R @ f/10 using a
STL-11000XM binned 3x3 for an image scale of 1.5" per pixel. Sub frame
of 800x600 was taken to cut download time rather than download the
1336x890 full image. That meant matching darks and flats. Something I
forgot about at the time and delayed processing. Even then the download
time stretched the time scale to about 3 minutes time for the 10 frames
used to make the animation. Mount was a Paramount ME controlled by The
Sky 6 Pro and CCDSoft 5. That guy
was really hauling ...
A 1.7 meg download so wait for it to animate.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
