Total Solar Eclipse at Ceduna, South Australia

moooooooo writes "The total Solar Eclipse on December 4 is fast approaching with Ceduna in South Australia being one of the better places to observe this rare event. Accomodation was thought to have been booked out but a new site has been set up where you can find more information on the event. Information can be found here and accomodation info is at the bottom of the page. I heard on the radio that they will be setting up a "tent city" for those of us who want to camp out." There's a very impressive eclipse page describing the orbital conditions necessary for an eclipse and listing solar and lunar eclipses coming up.

    staring directly at a solar eclipse is not a good idea..

      actually you can stare at a Total eclpise without having to worry about your eyes burning out at all. Its when you view a Partial Eclipse that you will burn your eyes. When the eclpise you can start to view it without protective eye wear. You can even look at it with a telescope. But beware it will only last a few minutes some times even less and then you had better put on your eye protection again.

      When you are viewing a total eclipse what you see for light is actually the Corona of the sun.

      At Start and end of totality, light from solar surface passes through Crevices at the edge of the moon, producing Bailey's Beads(Points of light at the edge of the moon) or a diamond ring effect(One bright spot set upon the silvery corona)

      It is actullay quite amazing though I have never viewed one in real life I seen one on a video in my Atronomy class in university

      A total eclipse is rare because it takes about 54 years and 34 days for the total eclipse to return to (almost) the same area.

      it takes 18 years, 11 and 1/3 days to occure again but it will happen 120 degreese further west due to the rotation of the earth durring that time.

      I disagree; Bailey's Beads aren't that bright, and they appear gradually enough for you to look away. If you keep looking after that without putting on some protective gear, well, it's your own fault.

    I know everyone here probably knows what an eclipse is, and you all probably appreciate the grandeur exhibited by shadows created with celestial entities.

    But I myself wasn't quite sure why Ceduna in southern Australia was a good place to view it. However, after some research, I found the following information:

    To witness all that this total solar eclipse has to offer, viewing must be within the narrow path of the moon's umbral shadow, which passes directly over Ceduna.

    Although the sun will be partly eclipsed throughout South Australia, and 88% eclipsed from Adelaide, the spectacular effects of this eclipse will not be visible outside the shadow's path due to the intensity of remaining light from the sun.

    Even 99% eclipsed gives you much less than 99% of the 'total eclipse experience'!

    The bottom line: if you are in your parents' basement at the time, you will miss the total eclipse.

      Having 'seen' many partial eclipses, and then having gone to Hungary for the 8/11/99 Total Eclipse (we had just over two minutes totality) I have to whole heartedly agree. Though personally I would use the analogy of virginity rather than pregnancy.

      While partial solar eclipses and total Lunar eclipses are entertaining, I can only describe the total eclipse in superlatives like mind-altering, orgasmic, cosmic, spiritual, etc.

      I would disagree that all partials are interchangeable though. You have to get to something like 40%+ to really notice the lensing effect of the natural pin-hole cameras created by leafy trees (little crescent moon shadows are cast on the ground); and you have to get to somewhere like 90% for weather effects like the wind picking up or a noticeble change in temperature - or for the reaction this has on animals like the birds going quite.

      I would eventually like to experience an anular eclipse - which is also a type of partial eclipse, which I imagine will be much like like a total eclipse though I doubt it will be quite the same. My guess is it will be somewhat analogous to sex with a condom vs. sex without a condom. For one thing, you can't view an anular eclipse without protection, like you can a total - so like sex with a one night stand vs sex with your spouse, perhaps?

But what might seem unique could be the result of ignorance or lacking imagination: we just don't know of other examples. Also, things that are similar are only so for a brief time. The orbits of the Earth and Moon have changed over time. The Moon used to be much closer to its planet, and is gradually drifting away.

I have NEVER seem a photograph do justice to the experience. Not only do photographs fail to present the full dynamic range of the visual, they lack the wind, the temperature drop, the effect on plants, birds, insects, people ... You really have to see and experience a total solar eclipse directly.

    Each eclipse is unique. The shape and size of the solar corona. The colors. Solar prominence positions, shapes, rates of change. Sky brightness. Duration of the diamond rings. Shadow edge sharpness. Shadow band size and change rate. etc. etc. No two eclipses look the same.

    The eclipse near/at Ceduna will have some special features. The short duration is a result of the moon and sun being very near the same size. Long eclipses (such as up 7+ minutes) allow for observation of the inner corona (near the solar disk edge) only near the beginning and end of the Eclipse. Short eclipses offer excellent inner corona views throughout the eclipse. There is a trade-off between inner detail and duration.

    The eclipse will be near sunset. The same optical illusion that makes a full moon near the horizon seem large makes the solar corona (sometimes 2x to 4x the apparent size of the sun/moon disk) seem huge.

    The Sun will set after totality ends but while the moon is partially covering the solar disk. We will watch a crescent sun set. Instead of watching a single point wink out, we will watch two points wink out one after the other. Some are hoping to see a double green flash.

    The Sun should be entering quieter phase of its sunspot cycle. But for the last few months we have seen an unusual degree of activity this late in cycle. A more active sun frequently results in a non-uniform shaped corona. A more active sun frequently results more and unusual numbers of solar prominences.
