Pi of the sky frame view

In the 8^th of November 2011 the planetoid 2005YU55 passing close to the Earth. According to the NASA and the Minor Planet Center, the shortest distance between 2005YU55 and our planet was lesser than 125,000 km (less than 78,000 miles) and reached brightness of 11 magnitudo.

The planetoid was hardly visible from Europe, but well visible from South America, where in Chile there is one of ours detectors. Cameras in San Pedro de Atacama took a series of 10 seconds exposure under almost Full Moon conditions.

Below there are two sets of frames from November 8^th 2011, about 1:40 UT, covering 2°x2° of the sky. The 2005YU55 crosses centre of the field of view. First appears in frame No 8, moving from the right edge toward the left and leaves field of view in frame No 72. In this moment the planetoid crosses the constellation of Pegasus, near Delfinus and Equuleus borderland (coordinates about RA: 21^h 35^m, Dec = +15° 32′):

There are animated gifs available, with all of above frames with printed time (UT) and position of the planetoid: k2a camera, k2d camera.

In the second set of frames there is shown path of the planetoid more or less half an hour later. To this time the planetoid moved almost 5° East to coodrinates RA: 21^h 56^m, Dec = +16° 34′ going inside the Pegasus constellation. This time frames are 4 times bigger and cover 4°x4° of the sky. The planetoid appears in frame 2 (better visible in frame 3) a few mm up from the middle of the right edge of the frame, and dissappears in frame 139:

Animated gifs are available as well: k2a camera, k2d camera.
