Yep. Nothing to it.
Like a lot of Tom's amazing results, there was some
planning involved, but the tools exist to let you do it,
so you could try it a few times to figure out how to do it
yourself. I think also Tom was doing this of thing before
the nice robo scope came along. There will be more of
these things coming along --- watch this space!
Wow, Tom. Wow.
I agree. Maybe another time you can try getting
a rotational lightcurve. Possibly only a few minutes
rotation period for such a small rock. Last February
Lowell postdoc Dagmara Oszkiewicz (with a little coaching
from me) got a lightcurve for an SUV-sized asteroid moving
past 40 degrees/day using the Lowell 72-inch telescope.
I didn't think we could get something going that fast
with this 90-year-old telescope because of its huge image
scale (32 _meters_ focal length!). But we just tried it,
and mainly thanks to NAU researcher Michael Mommert's
slick photometry software, it worked. The rotation
period was a little under 3 minutes!
