(6708) BOBBIEVAILE
D. Pray, Carbuncle Observatory, W. Brookfield, MA, U.S.A. et. al., 
report that photometric observations obtained Apr. 16 to May 3 reveal 
that minor planet (6708) is a binary system with an orbital period of 
24.7 hr according to CBET 1794.  The primary shows a period of 8.221 +/- 
0.002 hr, assuming a bi-modal light curve, and it has a light curve 
amplitude of 0.08 mag, suggesting a nearly spheroidal shape.  Mutual 
eclipse/occultation events with a depth of 0.31 mag indicate a lower 
limit on the secondary-to-primary mean-diameter ratio of 0.57.

Observatory 1.5-m telescope shows it to be a type-II supernova.
