Lunar Eclipse | 27 Sep 2015 | Tetrad Part 4

Previous posts about this tetrad of lunar eclipses can be found by following this link. Visit those links for explanations of the phenomenon if you need them.


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.

  1. It’s iffy, at best. Rain is forecast here for Sunday night, so it will be a wait and see situation. It’s a shame, since the time is good for families with little kids. (It’s good for big kids, too.)

    • I hope it is clear for you. The east coast may have problems with the storminess. We will likely be ok here.

      It is a good time for getting kids out to see it. I hope people will do that.

  3. Love that image you took Jim, and the video clearly explains what happens. Thanks for that. Since I live by the ocean, I’m going to be looking out for the tides, as they intrigue me. I’m trying to understand them, as I’ve read that there are two high tides, and two low tides in just one day. Since I live by the ocean, I’m trying to become aware of this. However, all I get to witness are usually three tides, because moonrise times are never the same. In the mornings, the tide can be very high at times, just as it can also be low, however. So it all depends on the moonrises, but also on atmospheric conditions. A change occurs while I sleep, so I don’t see that. I expect to see a low tide tomorrow, as the supermoon rises; then as it rises to its perigee, a high tide should come in (but it could be late in the night). Does that make sense?
