Above is a movie showing the 30-meters large near-Earth asteroid 2014 DX110 just around the time of its minimum distance from the Earth (about 350.000 km).
102 images were taken back to back, each exposed for 3 seconds, remotely using the Planewave 17 robotic unit part of the Virtual Telescope. The Paramount ME robotic mount was tracking the apparent motion of the target, providing an exceptional performance and effect, as usual.
Asteroid shows brightness variations, as it is fast rotating in a few minutes, so reflecting a variable light from the Sun. Around there are some hot pixels, too, they are just due to the imaging camera electronics.
At the imaging time, this rock was apparently moving with a rate of 515″/minute. Images were taken as part of the live session shared online.
