    This weekend, a "time traveling" solar eclipse will turn the familiar disk of the sun into a ring of fire for sky-watchers in parts of Asia and the U.S. West.

    Known as an annular eclipse, the event is the first of its kind to be visible from the mainland United States since 1994. The region won't see another such eclipse until 2023.

    Like a total solar eclipse, an annular eclipse happens when the moon lines up between Earth and the sun. But in this case, the dark moon's apparent diameter is smaller than the visible disk of the sun, leaving a ring—or annulus—of fiery light around the edges. (See annular eclipse pictures.)

    During such an eclipse, "the path of annularity, where the full eclipse will be visible, is hundreds of miles wide and thousands of miles long," said eclipse
    expert Jay Pasachoff, the Field Memorial Professor at Williams College in Massachusetts.

    In this path, "viewers looking through special solar filters can see a ring of sunlight around the black silhouette of the moon," said Pasachoff, who is
    also aNational Geographic Society grantee. (National Geographic News is a division of the Society.)
    The annular eclipse starts in China at local sunrise on May 21. The path of the moon's shadow then goes over Japan around 7:35 a.m., local time, and
    races across the Pacific Ocean.

    (Also see "Eclipses in Ancient China Spurred Science, Beheadings?")

    Due to the time zone change, the eclipse makes landfall again in North America in the late afternoon of May 20, starting at the California-Oregon
    border at 6:26 p.m. PT.

    The annular eclipse then crosses southern Nevada, southern Utah, the Grand Canyon in northern Arizona, the lower-left corner of Colorado, and most
    of New Mexico before ending in the area of Lubbock, Texas, around sunset at 8:36 p.m. CT.

    For most viewers in the path of annularity, the eclipse will last for a just over four and half minutes.

    Active Sun to Add Beauty to Eclipse


    Some picturesque wilderness areas—including several U.S. national parks—will be in the 190-mile-wide (300-kilometer-wide) path of the full annular
    eclipse.

    Viewers in a broader track stretching for thousands of miles across northeastern Asia and the western two-thirds of the U.S. and Canada will instead
    see a striking partial eclipse.

    "Unlike a total eclipse, in which the sun is entirely covered and the sky therefore gets dark, it never gets dark during an annular eclipse like this one,"
    Pasachoff said.

    "So the only loss in view from being off to the side of the zone of totality is that you won't see a complete ring and things won't appear symmetric,
    but you'll still be able to see a partial eclipse of the sun."

    (See partial eclipse pictures.)

    The best chances for clear skies during the event will be in states such as Nevada, Arizona, and Utah, added Anthony Cooke, an astronomer at the
    Griffith Observatory in Los Angeles.

    "But most of the path in the Western U.S. has better than even odds of clear enough weather to observe the eclipse," he said.

    Cooke also predicts some added beauty with this eclipse, since it occurs close to the expected maximum of the current solar cycle in early 2013.

    "We can expect interesting moments when sunspots of various sizes will be covered by the advancing limb of the moon, then later uncovered as the
    moon retreats from the sun's face," he said.

    (Related: "Solar Eclipses Can [Slightly] Change Weather on Earth.")

    To view the eclipse safely, astronomers recommend using either a professionally manufactured solar filter in front of a telescope or camera, or using
    eclipse viewing glasses that sufficiently reduce the sun's brightness and filter out damaging ultraviolet and infrared radiation.

    But probably the safest and easiest way to take in the eclipse is to use the pinhole projection method, Williams College's Pasachoff said.

    "Punch a one-eighth to one-quarter-inch hole in a piece of cardboard and use it to create a projection of the partial or annular phases on a wall a few
    feet away," he said.

    Eclipse as a Science Tool


    The Griffith Observatory's Cooke says scientists will probably also be making use of this weekend's annular eclipse.

    (Also see "Eclipse Expert Makes Hot Finds in Sun's Darkest Hour.")

    "Radio telescopes close to the path of annularity will make observations as the moon passes over sunspots and other sources of radio disturbances on
    the sun," he said.

    Sunspots are linked to eruptions of intense electromagnetic radiation called solar flares, which can cause disturbances to radio communications on
    Earth and also hinder radio astronomers' views of the universe. (Find out more about solar storms in National Geographic magazine.)

    "Also," Cooke said, "precise timing of the onset of annularity can provide data on possible changes in the diameter of the sun when compared with
    historical measurements."
    Live feeds will be set up. One of them is in the source. Pictures are also in the source.

    Will I seriously go blind from looking at it, or is it like that 'don't look at the sun' bullcrap where you're not blind but you see spots everywhere for a while.

    Is this one of those eclipses that allow you to see the stars next to the sun so that you can measure how much the light coming from the star is warped by the sun?

    Good luck with that. I don't think that will end will what with the whole staring at the sun the most stereotypical way to go blind.

    Right as it hits I'm going to put my eclipse glasses on and scream, "YEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHH !"

    Not sure if these have been posted yet, but I'll post them here.

    Use this site to put the city you live in, to see when the eclipse starts and ends for you (assuming you'll see it), and how much of an eclipse you'll get.

    You can use this livestream to see the eclipse. The first one, over Japan, is in about 20 minutes. They'll have a later one somewhere in the USA, but I'm not sure exactly when that one will play.

    THIS MY FUCKING GOD. The whole week has been beautiful but now it's raining and supposed to rain all day. Fuck Washington State, it produces nothing but shitty apples and fucking rain. I was all hyped since I've never seen an eclipse before, too. Me and a friend were gonna watch it together but fucking Washington decides that now is the time to rain.

    I'm probably a bit late here.

    Bright visible light isn't dangerous even though it may feel painful. It's invisible UV light which causes all the damage. The pain you experience when looking at a bright light is supposed to protect your eyes from UV radiation.

    Looking at the sun normally is safe enough because your eyes adjust to the light. However during a solar eclipse, the corona doesn't shine very brightly in the visible spectrum - it's relatively more intense in the UV spectrum. Your eyes won't adjust, and they can get burned.

    I thought it was the infrared light that fucked you up. The NASA website isn't coming up, but it said on there that it was infrared light that caused the burning.

    Vancouver is just a stone's throw away from Washington, so I count him as a Washingtonian in this case.

    Well, apparently the livestream I posted sucks dick - it's not an actual livestream it seems.

    this one is an actual livestream (they're streaming right now, and come on to talk every few minutes). The clouds coverage is less than ideal, but hey, they're clearer than Washington at any rate.

    The eclipse is about 50 minutes from now, using THAT stream.

    if you're on the SLOOH cam, switch over to the NAOJ station on the stream window. it's got pretty good coverage.

    Probably not, unfortunately. http://www.wsdot.com/traffic/weather/ You might get some sun at Yakima or Tri-Cities, but everywhere else is engulfed in clouds.
