The NEO (357439) 2004 BL86 (Orbit type: Apollo ) (estimated to be 440–1000 meters in diameter) will safely make a Close-Approach of 3.1 Lunar Distance on 27 January 2015. This will be the closest "known" Approach by something this large (H = 18.8) until 2027, and may will briefly peak at around apparent magnitude 9. It has been schedule for Goldstone Observations(2015 Jan 27-Feb 1).
