Important Notes About Movies

Please note: That movie 1, although interesting, IS NOT the newly discovered double. It is showing the performance of our technique on a known asteroid, that looks like it is close to being a double, but actually is connected.

Movie 1. This is a movie of the rotation of asteroid 216 Kleopatra in Nov 1999, when radar data were also beign acquired, that showed the weird 'dog-bone' shape of this asteroid. These data are from CFHT. The asteroid rotates once every about 5 hours.

Movie 2. Newly discovered main-belt double asteroid 90 Antiope as it rotates completely every 16.5 hours.
