Observer details:
568 Mauna Kea. Observers C. Veillet (K01QT7T, 3.6-m Canada-France-Hawaii
telescope), S. S. Sheppard and Y. R. Fernandez (K01RE3Z, K01U18O, 2.2-m
University of Hawaii telescope). Veillet's preliminary reduction confirms
K01QT7T's binarity (IAUC 7733), the fainter component being at a separation
of approximately 0.86 arcsec in p.a. 318 deg.
