Got binoculars? Make some science.
This Saturday night a bright star in Taurus will be occulted (eclipsed) by the moons of the asteroid Eugenia. Yeah, that's right, the moons of an asteroid. If you didn't know asteroids had moons, check this out. Anyway, observers in the southern US and Mexico can help astronomers determine the positions of the moons by--get this--watching the star go off and on and noting the times. For this, even the largest telescopes on Earth are less useful than you are, as long as you have binoculars, a timekeeping device, and some idea of where you are. Details here, instructions and finder charts here (scroll down to the hideous yellow part).
