Lunar eclipse Definition and 21 Threads

Anyone else watching the lunar eclipse tonight? It starts at about 9:30PM EST, with totality at 11:41. It's cold and windy in PA, but at least it's mostly clear. Here's a couple of pre-eclipse photos:

Can total lunar eclipse and partial lunar eclipse be happened at the same time? So, do we call it partial lunar eclipse when the total lunar eclipse happen just before?

hello

Taken by Griffith Observatory. Four hours of footage has been compressed to 60 seconds. The moon set while the partial eclipse was not yet over.

Hello, I don't see any other post about tonight's full moon and lunar eclipse, so I thought I would mention it.

Hi, Just wondering: The lunar orbit around the Earth is tilted 5.1 degree with respect to the Earth's orbit around the sun (as described in the video), so only at 2 times during the year the Earth is aligned with the sun such that lunar eclipses can happen IF the moon is behind the Earth...

hi guys and gals a total lunar eclipse will be visible for all Pacific and parts of it for most of USA parts of South America, Central Asia cheers Dave

Homework Statement Find the radii of the umbra and penumbra circles drawn drawn perpendicular to the EMS axis, formed at a distance equal to that of the moon from the Earth. Homework Equations (From: http://www.opticiansfriend.com/articles/equations.html#Shadows) D2 / L1 = (P + U) /...

If during a solar eclipse the moon tapers one moon diameter, wouldn't a lunar eclipse taper one Earth diameter?

Being on the east coast of the US, I won't be able to see it. Those on the west coast will though. Here is how it will happen. Once in a blue moon, the Earth darts out of its orbit temporarily and blots out the sun. When that happens, you can see all of the sunsets on the Earth reflected off the...

About the wave nature theory ! In the case of Lunar Eclipse Hello all :) First I'm glad to be a new member of this forum .. Anyway .. as I noticed that if someone thought about a theory or a physics inquiry you share your thoughts and solve the problem .. So what came to my mind months ago...

Last nights total Lunar eclipse was probably the first time a great many people even paid any attention to our natural satellite for quite a while. It's kind of taken for granted. After all, except for the passing phases, it usually doesn't change. Its the same face staring at us night after...

I guess many have watched the lunar eclipse last night I was just thinking about the duration of a lunar eclipse on my way home sun-to-earth = 1.5x10^8 km, moon-to-earth = 384400 km R(Earth) = 6378 km, R(Sun) = 6.96x10^5 km, R(Moon) = 1378 km Moon's period around Earth = 27.3 days x /...

PF member turbo-1 predicted that some superstitious Red Sox fans would attach some mystical significance to the lunar eclipse during the final game of the World Series. So far, fortunately, I have not seen too much of that in the news, although I have not asked many fans about it. I did find...

Hi, I was fortunate to be camping on November 8 and near a nice warm fire throughout the entire lunar eclipse. It was awesome! I have a question about the the apparent direction the moon appeared to travel through the Earth's shadow. This is kinda hard to put into words, so please bear...

I stumbled on this page while reading the weekly celestial weather report. http://astrosite.com/__JM1.htm the star of david is present at the exact moment in an astrological chart that the Earth experiences a total lunar eclipse on 11/8/2003...

Lunar eclipse tonight (15/16.5) and I found this night calculator http://aa.usno.navy.mil/data/docs/LunarEclipse.html that allows you to get information on the eclipse, and future eclipses.
