Supermoon Eclipse!

Finally!! A celestial event that is both at a reasonable hour and visible from home. How often does that happen? I’m of course talking about the upcoming total lunar eclipse! I think Universe Today said it best by calling it the “Super-Harvest-Blood-Moon Total Lunar Eclipse.

So let’s start with Super. The moon’s orbit around the sun is elliptical, not circular. This means that it’s not always the same distance from the earth. On Sunday evening it will be at what is called Perigee, or at its closest to the earth. It will appear about 14% bigger than at other times.

Next up – Harvest. The Harvest moon is simply the closest full moon to the Autumnal Equinox which is when day and night are each about 12 hours long and the sun rises exactly due east and sets exactly due west. This was September 23.

Now the creepy – Blood. I have to confess  – I don’t really know much about this term. It has something to do with prophecies and apocalyptic whoo ha and frankly if you really want to know more about that you’re on your own!

And finally the big one – Eclipse!! This occurs when the sun is opposite the moon, and the moon, earth and sun are lined up so that the moon will pass through the earth’s shadow, temporarily blinking it out. The shadow has two parts, the Penumbra which is the dimmer outer shadow, and the Umbra which is the darker center. The moon will pass through both the penumbra and the umbra during this event.

Hopefully Lynn and I will be watching and recording all the necessary contact information and feverishly making sketches for our Luney II observing program. Or maybe we’ll just kick back in our lawn chairs and enjoy the show. Either way – it should be a great show!

Annual Picnic at Parmentiers

Small crowd at the annual astronomy club picnic Tuesday night. P9026915Maybe 20 this year, compared to 40 or 50 last year when the sun was shining. We’re betting it was the weather.

The picnic started at 6:30, and we were lucky enough to dodge the rain that had been predicted for picnic time and into the night. It was muggy, sticky and just generally unpleasant out there today.

However, despite the humidity hovering in the mid 90’s, we still had a great time.

Wayne cooked up all the burgers and dogs, and everyone bought a treat to share.

Amy and I left around 8:30, when Dick was setting up to show some amazing weather videos that Tony took at the Nebraska star party.

We already saw them when we were at the Minnesota star party. Plus, it was getting late on a work night, and we’re pretty whimpy. Yawn!
