Venus Regulus Conjunction

We've talked about the upcoming conjunction of brilliant planet Venus and bright star Regulus in the show, the Times column, and the podcast. The closest approach of the two will be in the early morning hours of Oct 3 (i.e., tonight), but the weather forecast is looking poor at this point. Here is what you'll see if we are lucky, or what we would have seen if it stays cloudy.

Venus will be about 150x brighter than Regulus, but Regulus is over four million times farther away! The two will stay together in the morning sky the rest of the month, with Venus sinking toward the rising sun and Regulus pulling away. The waning crescent moon will join the scene on mornings around Oct 12.
