An Occultation Event by Asteroid (973) Aralia Detected by TAOS

Dec 30, 2007

The star 2UCAC 47287546 (V = 11.4) was occulted by the asteroid (973) Aralia (V = 14.0, diameter = 52 km) at 14:57 on 30 December 2007 (UTC). This event was predicted by Steve Preston, and was expected to have a maximum duration around 4.9 seconds. Its shadow was expected to pass over Lulin Observatory in central Taiwan where the TAOS telescopes are located. Using high-speed [zipper mode] observations (5 Hz), the event was detected with the telescope TAOS B. The event lasted for 24 exposures, corresponding to a duration of 4.8 seconds.
