The asteroid 2016 RB1 was discovered (at ~ magnitude +19) on 2016, September 05 by Mt. Lemmon Survey (MPC code G96) with a 1.5-m reflector + 10K CCD. Asteroid 2016 RB1 has an estimated size of 7.3 m - 16 m (based on the object's absolute magnitude H=27.8) and it will have a close approach with Earth at about 0.1 LD (Lunar Distances = ~384,000 kilometers) or 0.0003 AU (1 AU = ~150 million kilometers) on 2016, September 7 at 17:20UT and it will reach a peak magnitude of about +12.3. Radio astronomers will try to observe it as 2016 RB1 could be a really strong radar target during its close approach.I performed some follow-up measurements of this object on 2016, September 07.6, remotely from the Q62 iTelescope network (Siding Spring, Australia) through a 0.4-m f/3.5 reflector + CCD. Below you can see our image taken with the asteroid at about magnitude +13 and moving at ~ 503 "/min. At the moment of its close approach on Sep 07, around 17UT, 2016 RB1 will move at ~ 2716 "/min (or about 45.2 deg/hour). The asteroid is trailed in the image due to its fast speed.
