Object name: 2013QR1
The potentially dangerous, recently discovered, Near Earth Asteroid, 2013 QR1 taken by me on August 25, 2013 at 3:52 through 4:26 UT in one minute frames. This was one day before closest approach. I was under a thunderstorm when it was closest in dark skies. The asteroid was estimated at 250 meters across and was moving about 1.57 minutes of arc per minute of time. The telescope was tracking on the orbital motion of the asteroid causing the stars to appear to move by the asteroid. North is up, west to the right.
