Moon Watch

The moon is in a waning (growing smaller) gibbous (more than half lit) phase. Last quarter is Friday, Nov. 10.

Venus and Jupiter

The best heavenly action this week is in the predawn sky. On Friday morning, look toward the eastern horizon around 6:15 a.m. You will be rewarded with ever-brilliant Venus 6 degrees above the horizon. Below Venus, closer to the horizon, is bright Jupiter, now entering the morning sky.

Even though Venus and Jupiter are low on the horizon, they are bright enough to be visible in a clear sky nearly up to sunrise, which is at 6:49 a.m. Friday. If the sky is especially clear, you can see the bright star Spica 11 degrees above Venus and red Mars 12 degrees above Spica. Thirty-two degrees to the left (north) of Spica is orange Arcturus, the fourth-brightest star in the sky.

On Saturday morning, also in the predawn sky, the waning crescent moon sits in the front part of Leo the Lion, just 1 degree to the west of Regulus, the brightest star in Leo.

Try to follow Venus and Jupiter the next few mornings as they grow closer together. By Monday morning, they will be only 0.3 of a degree apart.
