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!

  1. Hey, I was thinking that for future reference, it would be cool to let people know what time this sort of event will take place. Maybe include one particular time zone as a reference, or a link that provides information for several time zones.

    1. Hi Shelley – Thank you for your comment! It’s always nice to hear from one of our many readers. Sometimes I worry about sending someone outside to see something that they have no chance of seeing due to their location. We do have readers from all over the world! I will definitely keep your suggestion in mind the next time I share an upcoming event.
      Thanks again!
      Amy
