Part 4 of this tetrad takes place Sunday evening 27 Sep 2015 for North and South America. First evidence of the partial phase begins at 8:07 pm central daylight time. The total eclipse phase begins about an hour later at 9:11 CDT. Totality lasts a little more than an hour ending at 10:23 CDT.
The timing of this lunar eclipse is very good for viewers in North and South America. It begins when most people are still up. If sky conditions are not overcast, it will put on a show all evening. You do NOT need eye protection.
You don’t have to watch it continuously. Look every 20-30 minutes. You will see the Moon change color and coverage as it transits Earth’s shadow.
This is also a supermoon. It will be about 7% larger than normal because it will be closest to Earth in the slightly non-circular orbit. You will not likely notice it unless you have two photographs to compare such as these.
NASA posted this short video to explain what to watch for and when. May your skies be fair.
