Major Lunar Eclipse Sunday Evening

The moon will be offering a nighttime show on Sunday when it passes through the Earth's shadow, culminating in a lunar eclipse.  The effect will be a darkening...although not complete obscuring...of the moon...for around three hours for observers in the Eastern United States.  The total eclipse (the moon completely inside the Earth's shadow), for our EDT time zone, will be from 10:11 pm until 11:23 pm with the partial phases starting and ending 1-2 hours before and after.  The total eclipse will be visible in eastern North America, South America, western Africa and western Europe.  East Asia and Pacific Oceania will completely miss it, even the partial eclipse, because they'll be in the middle of the day when it happens...and you can't see a full moon at that time...

This event is being called the "supermoon eclipse" or the "super blood moon".  The reason for the "super" designation is that the moon will appear to be slightly larger than usual because it will be at its perigee (closest point in its orbit) to Earth, while "blood" seems to refer to the ongoing string of consecutive eclipses six months apart.  The earthsky.org website can furnish more information about this if you're interested...

If we're fortunate, the skies in Gainesville will be clear enough to watch this lunar eclipse, although in recent weeks a clear night sky hasn't exactly been something to count on.  I'd like to thank my Facebook and workplace friend Evelyn for having posted about this upcoming astronomical show, giving me some forewarning about it...
