My thanks to Bob Holmes of ARI for supplying me with his photos of the asteroid. The first picture is a series of timed lapse photos taken with ARI 32″ telescope showing the discovery. You’ll notice it’s a negative image, which is very common for astronomers to work with, since it makes for easier visual identification.
The second image is a from NASA/JPL Risk web page which shows the orbit
