Blood Moon 4 --- Totality--- Sept. 27-28

 Blood Moon 4 ---  Totality--- Sept. 27-28

Skywatchers will be in for  a super  show this  month as the full moon lights  the night of September 27-28.  It will  be a “supermoon” or a perigee full moon,  the moon’s closest approach to the Earth.

The moon does appear larger and brighter at perigee.  As if that weren’t  spectacular enough, on the night of Sept. 27-28, there will also be a total lunar eclipse.

A lunar eclipse can only occur during a full moon, when the moon is directly opposite the sun in our sky.  During a lunar eclipse, the  moon will pass completely inside of the Earth’s umbral shadow, casting the moon in a red-orange light–a Blood Moon.

This is the fourth Blood Moon  in two years– a lunar tetrad.  You can read about the first three here, here, and here.  A  lunar tetrad  is a relatively rare occurrence. The next such configuration will occur in 2032-2033.

The lunar  eclipse should be visible in North America (weather permitting). Here are the times for the Central Time Zone, courtesy of Earth Sky—

Central Daylight Time (September 27, 2015)
Partial umbral eclipse begins: 8:07 p.m. CDT on September 27
Total eclipse begins: 9:11 p.m. CDT
Greatest eclipse: 9:47 p.m. CDT
Total eclipse ends: 10:23 p.m. CDT
Partial eclipse ends: 11:27 p.m. CDT

EarthSky has  times for other locations here.

A  lunar eclipse is  a moving and mysterious sight.   This is something you won’t want to miss!

How about an eclipse party?  There will be free family events planned  at the Adler Planetarium.  You can find out more here

In case of rain or overcast sky, there  will be live webcasts online. You can  follow along at Sky & Telescope here.

  • For a change, it is around here when we're still awake to see it.

    Thanks for reading, Jack. It should be quite a sight, weather permitting...

  • Thanks for the update. It's another reason to wish for an end to the stormy weather. Don't know whyyyyyy..... (Sorry!)

  • In reply to Margaret H. Laing:

    Thanks for reading. Hope you're enjoying the fabulous weather today!

  • I hope we can all see it, it sounds fabulous!

  • In reply to Kathy Mathews:

    Thanks for reading, Kathy. I hope it's a good night for moon-viewing!

  • After all the meteorologists repeating "it will be too cloudy to see it," the weather was clear. I could see a bite taken out of the "north side" of the moon, and then near totality only the bottom crescent showing. However, size wise, it didn't look like a super moon.

    So glad you could see it, Jack. Even with all the hype, it was impressive...
