(52768) 1998 OR2, 11-25 April 2020
Near Earth asteroid (52768) 1998 OR2 passed about 6.3 million km from the Earth on 29 April 2020. The object is potentially hazardous on a timescale of thousands of years and is notable for its large size, at over 2 km diameter. On 25 April I was able to image it in Sextans, at magnitude 11, moving south at over 14 arcminutes per hour (7 arcseconds in each 30 second exposure).
The attached animation shows the motion of the asteroid. Occasionally it appears to vanish: that's when the guider lost control and the frame could not be used. The two stills present its motion in slightly different ways.
