Hello David and Skip and Arizona astronomy friends,
I enjoyed your reports and great images of the fast 3122 Florence flyby
and other recent asteroid flybys, too!
Since you are experienced observers of asteroid flybys, I invite you to
catch the flyby of the _OSIRIS-REx asteroid sample return spacecraft
from Sept. 10-22_ during its Earth Gravity Assist maneuver. The
spacecraft is expected to be first visible at 23rd magnitude without
much lateral motion and brighten to about 11th magnitude as it
slingshots past Earth. See here for information for your location:
https://ssd.jpl.nasa.gov/horizons.cgi#top. Use "ORX" for target body. ;
Watch the mission website next week for official press release on the
EGA maneuver and image submission form: http://www.asteroidmission.org/.
Best regards and _/clear skies!/_
Dolores Hill (and Carl Hergenrother)

There will probably be many reports of observations, and a few images.
I tracked this object tonight for an hour, as it passed by SAO 145171,
between 9:30 PM and 10:30 PM.
You can see my results (a stack of 60 images, each 45 seconds long, with a 15
second âspacerâ between each image, here:

We got a good view of this very bright fast-moving asteroid--
between clouds tonight during the Lowell evening public-program
telescope viewing. We used the 16-inch McAllister telescope.
Since the telescope is under computer control, we simply
keyed-in the current ephemeris position and also tracking
rates --- the asteroid was moving about half a degree per hour.
Shortly after 8pm it was brighter than mag 9, and was the
brightest star in the field. It was even visible through
he 4-inch low-power finderscope, so this is not a challenging
object in terms of brightness, even with the bright Moon and
murky sky. Best of all was being able to show the asteroid
to a few dozen visitors, and explain about tracking near-Earth
asteroids and related science.
