Skip to comments.BIG LUNAR ECLIPSE..(Saturday morning, June 26th)
Posted on 06/25/2010 1:58:50 PM PDT by TaraP
This Saturday morning, June 26th, there's going to be a lunar eclipseand for many residents of the USA, it's going to be a big one.
The eclipse begins at 3:17 am PDT (10:17 UT) when the Moon enters the sunset-colored shadow of Earth. By 4:38 am PDT (11:38 UT), the moment of greatest eclipse, 54% of the Moon's diameter will be covered. From beginning to end, the event lasts almost three hours.
In Addition: A solar wind stream flowing from the indicated coronal hole could reach Earth as early as June 26th.
Am I correct in assuming that the eastern part of the US will not be able to see anything, even with clear weather, because dawn will have already arrived?
save me some time....anything to view in Khonectikut
woops disregared my prior trans.....(over)
Big Lunar Eclipse?.....Big earthquake.
It may be total occurrence below the horizon but I'll keep my eye on it!
so 10:17 pm UT is 5:17 CDT? That measns it starts here in Chicago in about an hour?
No...1:17 am. here in Chicago
A lunar eclipse and a full moon all in one day.
I believe lunar eclipses only happen at a full moon.
Thanks for the map. Please explain the meanings or P1, U1, U4, and P4.
Right! Not always eclipses, though. LOL, you’ll have to excuse me with all the lunar activity.
Yes, I believe you are correct, or at least very close to full moon.
By virtue of the positions of the Earth, Moon and Sun at the time of a lunar eclipse, by definition, a lunar eclipse can only happen during a full moon. Conversely, a solar eclipse can only occur during a new moon.
If anyone has a link to some place where the scientifically challenged can find the local times for this can they post it?
Ack, I’m also reading challenged. It’s described above, sounds as though it starts at 3:17 Pacific time tomorrow morning.
For earth-bound observers, the penumbral stage is not very striking--the moon's surface should be somewhat darker than normal but you're seeing a part of the moon that is still getting some sunlight. The umbral phase is darker and more noticeable.
From the map, it looks like the moon sets over Chicago shortly after the start of the umbral stage, so it may not be worth getting up early for. Even in the Pacific time zone, the eclipse will be partial--the earth's shadow will be noticeable but won't cover the entire earth-facing surface of the moon.
Two weeks from now (July 11) there will be total eclipse of the sun, but the path of totality goes mostly over the south Pacific--totality will be visible from Easter Island and from some remote parts of southern Chile and southern Argentina (assuming the skies are clear).
The P1 line represents where the penumbra begins to be visible at moonset. The U1 line represents where the umbra begins to be visible at moonset. Between those two lines people can see only the penumbral phase. The U4 line represents where the umbral phase ends at moonset, and the P4 line where the penumbral phase ends at moonset. West of the P4 line people can see the entire eclipse...but of course it is only a partial eclipse.
Thanks for the info. I thought that was it but wasn’t sure. Now what do the “1” and “4” in the notion on the map indicate?
