    IIRC there is another total solar eclipse in the US from north to south in 2026. It will roughly follow the Mississippi river I believe.

    The 2017 eclipse should be good. August is a great month in Oregon, and I may climb Mt. Jefferson that day. :-) That eclipse goes west to east pretty much across the whole country.

    I thought this was no coincidence, that a full lunar eclipse was only possible when the moon is on the far side of the earth from the sun, which is when it appears full. no? astonomers care to comment?

      If you're still interested, checkout Encyclopedia Brittanica's article on the frequency of solar and lunar eclipses. Also, they have a rather technical, but very interesting article on the predictions and uses of both solar and lunar eclipses - including methods to prove General Relativity. I realize this is slightly offtopic, as some of it pertains to Solar eclipses, but its something Im interested in:)

    I just want to say that I have to agree with you. But if you want to see a total solar eclipse, you should plan on travelling to go see one.

    I've seen several total lunar eclipses, and partial solars, but only one total solar eclipse (this one last summer on 8/11, from Hungary.) There is absolutely no comparison as to the profound effect seeing the sun blotted out and replaced with a glowing circle of white fire had on me, versus the mere curiosity of the lunar and partial solars. I can only describe the total eclipse in such superlatives as: a religious experience, an epiphany, or orgasmic. It literally left me trembling in awe and questioning my own place in the universe.

    As for the total lunar eclipses, and partial solars, I would describe them in terms such as: Hey that's cool, the moon is red! or, Wow pretty neat, if I look at the sun's shadow there is a bite taken out of it!

    If you wait for the total solar to come to you, who's to say you won't have cloud cover that day, or perhaps smog if you live in Southern Cali. Find a listing of total eclipses and choose one soon that will pass over a location you would like to trave to anyway. It may take a couple of tries, but eventually you will be treated to the experience of a lifetime.

    It would disprove their theory if it actually happened, which I seriously doubt. The moon remains the same size in the sky.

    To test this, hold a dime a certain length away from your eye when the moon looks big, so that it just covers it. Then hold it the same distance away when it looks small, and it'll still just cover the moon.

    Yes, all lunar eclipses occur when the moon is full. Think of it this way, the only way that the earth can block the sun's light from getting to the moon would be if the sun was at 6-O'clock, and the moon was at 12-O'clock (using that crazy military reference where 6-o'clock is exactly behind you and 12-o'clock is exactly in front of you).

    The greatest irony is that the moon is at it's fullest at precisely the time that we can't see it. When it is totally eclipsed.

    Our atmosphere is acts bit like a lense, and bends refracts some of the light on to the moon. The amount of light that is defracted thus, therefore the brightness of the moon on during the eclipse, depends on the quality of earth's atmosphere on the day of the eclipse.

    If the atmosphere is all full a volcanic ash, or smoke from big forest-fires etc., then the light of the moon would greatly diminish.

    Every new-moon has the potential for a solar eclipse, and every fullmoon for a lunar one. However, given that the moon is pretty small compared to earth, during solar eclipses, the shadow of the moon might miss the earth completely. The moon is not that lucky to get out earth's shadow. Therefore, more lunar eclipses are visible than solar eclipses. For the folk on the moon, our lunar eclipse is a solar eclipse, and our solar eclipse is, errr, terra eclipse perhaps.

  17. ``North America''? by David+A.+Madore · · Score: 3

    Excuuuuse me? What in the world does it mean for a lunar eclipse to be ``in (for) North America''?

    This would make sense for a solar eclipse, since solar eclipses are very localized, but a solar eclipse happens at the new moon, whereas a lunar eclipse happens at the full moon (for obvious reasons).

    A lunar eclipse is visible throughout the hemisphere where it is night (which, of course, is the same as the hemisphere where the moon is visible, since the moon and the sun are in opposition), so at best the ``north'' in ``North America'' is out of place.

    This fact (that lunar eclipses are visible from half the world whereas solar eclipses are visible from such a small region) makes lunar eclipses seem much more common than solar eclipses; in fact, the contrary is true. The last total solar eclipse in the world was on August 11, 1999 in Europe (I was there), and the next one is next year in Madagascar.

As a result, on January 20'th of your year 2000, the full moon will experience color and brightness difficulties that significantly deviate from the published standard.
