Supermoon Watch Party on Nov. 13

A rare “Supermoon” will be visible from Innsbrook starting this Sunday evening, November 13, 2016. We will have an informal watch party on the Lake Alpine Dam starting after dusk around 6 pm, weather permitting.

What is a Supermoon?  The Moon’s orbit around the Earth is not a perfect circle, but elliptical, with one side closer to Earth than the other.  As a result, the distance between the Moon and Earth varies through the year.  When the Moon is at its closest, it’s called “perigee”.  When it’s furthest away, it’s called “apogee”.  When a full moon coincides with perigee, being closest to the Earth, it’s called a Supermoon.  In fact, the moon hasn’t been this close during full moon since 1948 and won’t be again until 2034.

According to’s article “Supermoon November 2016:  When, Where & How to See It”, the Supermoon will look about 14% larger than an average full moon, and an impressive 30% brighter. More information at

A favorite place for us to watch the rising moon, as well as planets and constellations, is from the Lake Alpine dam. This location offers the most expansive horizon in all directions of Innsbrook. This time of the year you will also hear coyotes howling across the Tyrolean Valley, seemingly in competition with each other. Let’s see if a Supermoon really brings them out!

Hope to see you on the Alpine Dam after dusk, around 6 pm, on Sunday evening, weather and clear skies permitting of course. Just a note that if Sunday evening is cloudy, Monday evening should be good viewing as well since the full moon and perigee are technically on Monday morning.
