Good time to see the morning stars?

You're a bit late to see all of them. Mercury and Venus are both pretty much gone behind the Sun, but Mars and Jupiter are well placed. The best time is around 4 a.m. EDT, looking east and northeast. Any later, and the Sun's light will flood the sky. Jupiter is the brightest object in the sky, but Mars is a bit harder to spot, directly under the Pleiades. Tomorrow morning the waning crescent Moon will be nicely framed by the Pleiades and Jupiter, with Mars down below.
