What’s Up?

Harvest moon, supermoon, and partial lunar eclipse. What a night!

The full moon closest to the autumnal equinox is referred to as the harvest moon and will occur on Tues., Sept. 17. A combination of the harvest moon effect (when the Moon appears brighter a little longer due to the Moon rising closer to the same time several nights in a row) and the effect of the Moon at perigee (the Moon being closest to the Earth on its monthly orbit) may make it quite a spectacular September sight. Supermoon is the modern nickname of a full moon at perigee. September is the second of four supermoons in a row that we will experience. This supermoon will also have a partial lunar eclipse, with the Moon darkening slightly around 10:45 p.m. Capping the evening is gleaming Saturn hovering nearby for most of the night.

Space News: Europa

The launch for exploration of Europa, one of Jupiter’s moons, is aiming to take place Thurs., Oct. 10. NASA’s eagerly anticipated Europa Clipper will study the icy moon in a series of flybys as it orbits giant Jupiter. The Europa Clipper holds the honor of being the largest spacecraft NASA has yet developed for planetary exploration missions. When it arrives at Europa in 2030, we may be able to map the mystery of the subsurface ocean that scientists suspect is found on the moon.

How do I use the star chart?
Hold it out in front of you with the direction you’re facing at the bottom of the chart. It works even better if you hold it above your head and look up at it.

Why are east and west switched?
They are only switched because you’re used to looking at maps of the ground. Hold it above your head, and you’ll see the directions line up just right.
