Near-Earth Asteroid Makes Preview Appearance

Like trailers for the coming attraction, new images show asteroid 2012 DA14 on its way to a record-close approach to Earth on Feb. 15. One image, taken by amateur astronomer Dave Herald of Murrumbateman, Australia, on Feb. 13, shows the asteroid as a tiny white dot in the field of view. Another set of animated images, obtained by the Faulkes Telescope South in Siding Springs, Australia, on Feb. 14, and animated by the Remanzacco Observatory in Italy, shows the asteroid as a bright spot moving across the night sky.

Australia to have grandstand view of Asteroid 2012 DA14 and its near-miss with Earth

Experts have recommended people look below the Southern Cross about 4.30am AEDT onwards.
The best views will be on the west coast, though maybe not in Perth itself because of the ambient light. If you're in a rural area of WA, check the skies around 2.30am local time.
