AN ECLIPSING BINARY IN THE TRAPEZIUM

Every 65.4 days the eclipsing binary star Theta 1 Orionis A dims. It's the
westernmost of the four bright stars making up the Orion Nebula's famous
Trapezium. The eclipse takes roughly 20 hours to complete. At mideclipse
(which lasts 2.5 hours) the star is about 1 magnitude fainter than normal.

SPOT VESTA (AND URANUS)

Two solar-system bodies just below naked-eye brightness can be found with
binoculars in eastern Aquarius on October and November evenings. The minor
planet 4 Vesta loops through the dim "water streams" pouring from Aquarius
's bucket. Uranus, which is 10 to 13 times farther away, moves much more
slowly as it glows at magnitude 5.8 south of Aquarius's elbow.
