Description

The preliminary orbit with a short observation arc of 2 days showed that the asteroid had a very small chance of passing from the Moon or from Earth on about 23 October 2014. But with an observation arc of 10 days, the

(best fit) orbit showed that on 24 October 2014 the asteroid would pass (1.5 LD) from Earth and even further from the Moon. The asteroid peaked at apparent magnitude 13.5, placing it in the range of amateurs with roughly telescopes. It was removed from the Sentry Risk Table on 10 October 2014 using JPL solution #5 with a 10-day observation arc. It was observed by Goldstone radar on 24–25 October 2014.
