Elusive Mercury in the Evening December 1, 2017

This weekend promises amazing weather for December in SE Michigan. Take advantage of it by looking for the elusive planet Mercury!

Sunset on December 1 in A2 is at about 5:03 PM, and Mercury sets at about 6, so grab a pair of binoculars and go out between roughly 5:15 – 5:45 and look low in the SW. Be sure to check out Saturn too: it’ll disappear behind the Sun soon! The image below is for 5:30 on Friday December 1, 2017

As the days progress, Mercury gets closer to the Sun in the sky (yes, it’s in retrograde), so by the 5th or 6th it’ll be all but impossible to catch! Conjunction is on the 12th. Saturn conjunction is December 21. 01Dec1730SW_Mercury.png


Venus and the Beehive August 30, 2017

If you happen to be up around 6 AM local time the next few mornings (August 31 – September 2, 2017) grab a pair of binoculars. Venus skims past one of my favorite open clusters in the pre-dawn hours.

Look east, between the Big Dipper and Orion, just below Gemini. You won’t be able to miss Venus. It’ll even shine through light cloud cover! If it’s clear, point your binoculars that way and you’ll see the Beehive cluster, so called because it sort of looks like a bee skep tipped on its side with the bees buzzing around it (a skep is the round, woven grass type of beehive.) It’s a fairly bright cluster, so even a small pair of binoculars will do. You probably won’t want to haul out the telescope for this because you need a 2º field of view, which most telescopes won’t do.

If you live in really dark skies, plop a camera down on a tripod and try taking a 1 – 2 second exposure. Longer will capture more stars, but overexpose Venus.

Here’s a chart looking east at 6 AM on August 31 from Ann Arbor:

If it’s clear where you are this evening (or the next several evenings really), look high in the west about half an hour after sunset. That incredibly bright point of light you see is not a star, it’s Venus! If you happen to have a small telescope or good pair of binoculars, take a look at it. You’ll see it’s actually a crescent!

As long as you’ve got your telescope/binoculars out, be sure to check out the little red point nearby. That’s Mars. In fact, it’s pretty much a full Mars. How can two planets be so close in the sky and so different in appearance? Because one of them is nearby, almost between us and the Sun, while the other is far away, with the Sun in between.

Venus is brighter around February 16-17, 2017 than at any other time during its ongoing, approximate, 9.6-month reign in the evening sky.

Orionid Meteor Shower October 21, 2015

If it’s clear where you are, you might want to get up an hour or two early for the Orionid meteor shower. The peak is today / tomorrow (sorry I’m a little late for today), but it should be worth watching for a couple more days. Especially with the morning planets! Clear, dark skies are important for meteor watching, so you’ll need to get away from city lights.

Here in SE Michigan, the weather predictions make Friday morning look good. The Moon sets at about 3 AM, by which time Orion will be well up. However, if you wait until 5AM, you’ll get your chance to see Venus, Jupiter, and Mars. Mercury rises around 7AM, but by then twilight will have begun, which means it’s not as good for watching for meteors. The best hour is probably 5:30 to 6:30 AM.
