I recorded this close approach of asteroid 1999KW4 flying by the other night. I’ve finally worked out how to set my mount to track the asteroid itself and made this video as it glided safely past. BTW, its listed as a potentially hazardous object (PHO) because it can come within 7,500,000 km of earth at some time, which seels a long way, but is actually close enough to be of some concern should its orbit ever get changed!
