Venus brightest around February 16 | EarthSky.org February 16, 2017

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.

Viewing Comet Lovejoy January 8, 2015

Comet Lovejoy, C/2014 Q2 is about 4th magnitude right now. if your observing sight is dark, it’s easily naked eye. Urban observers aren’t so lucky, but it’s bright enough to be picked by a camera!

You’ll need a camera you can set the exposure and focus on (some smart phone apps will do that.) I strongly recommend a tripod since you’ll need an exposure of a few seconds.

Focus first on Jupiter: it’s bright enough to see through your viewfinder, and rises by the time the sky is dark enough to see the comet.

Once you’ve got a good focus, point your camera so Orion is on the left side of your view, and Taurus at the top middle. As it gets latter in the month, adjust the position so Taurus is on the left, and Orion is out of the view. Check the maps on the Sky & Telescope website for a more precise location.

Take exposures ranging from about half a second to about 15 seconds – the longer your exposure, the better the comet will look, but too long and the sky brightness may wash out everything.  You should have a very wide field image.

about 5 seconds…

Once back inside, you can zoom in and crop to get a better composed picture.

Of course, if your skies are this bad, adding a little guidance might help.

There's the comet! Really!

There’s the comet! Really!

Ok, you’re unimpressed. I can tell. But consider how bright those trees are. And, it was so cold my camera stopped working. Hey, if you think you can do better, prove it! Share your photos!

Oct 8 Lunar eclipse October 1, 2014

Between the department move, classes starting, and Kensington Astronomy at the Beach, I’ve been a bit too busy for the urban observing posts. I’ve started October though, so hopefully I’ll have that up soon.  In the meantime, here’s a bit about the lunar eclipse on Oct 8.

The wonderful thing about lunar eclipses is that you can see it from anyplace where it’s night and clear during the eclipse. The interesting part of the eclipse will be 9:15 – 12:34 UT on October 8.

For Michigan, it will be visible just before dawn in the west-south-west. The noticeable part of the eclipse begins at 5:15 EDT. You’ll want to get out there early, because totality begins at 6:27, and the Moon will be dim enough that you may have trouble finding the Moon in the pre-dawn light. Mid eclipse is 6:55, and sunrise will be around 7:40. The Moon sets 7 minutes latter. To finds times for your location, check out  http://www.timeanddate.com/eclipse/lunar/2014-october-8

A deeply eclipsed Moon is very difficult to see in the purple twilight.

Deepest eclipse occurs at 6:55 AM on October 8, when the Moon is about 8º above due west.

Usually, you don’t need anything be clear skies and darkness to see an eclipse. Dawn eclipses are a bit tricky though since the Moon disappears into the dawn light. A telescope that can track the Moon can be very helpful to keep the Moon in sight. If you don’t have that, a pair of binoculars can also help.

If you do have a telescope, swing it over to the eastern limb of the Moon. At 6 AM, Uranus will be just a bit north of due east and about 1º (or 2 Moon diameters) away. By 7AM it’s only half a degree and due east, but the sky will be starting to brighten (H/T Abrams Planetarium Sky Calendar – I didn’t notice this conjunction!)

Uranus is about 1º off the eastern limb of the Moon at 6 AM. By 7 AM, it is only half a degree away but to the SE.
