Close conjunction of the Moon and Jupiter

Look for a bright "star" unusually near the waxing gibbous Moon this evening. The Moon passes less than 1° from it for most of the U.S. and Canada. Think photo opportunity; use a long lens, or zoom to the max. In much of South America the Moon actually occults (covers) Jupiter.

Although they look close together, the Moon is only 1.3 light-seconds distant from Earth, while Jupiter is 1,700 times farther away at a distance of 37 light-minutes.
