As long as you don't look at the sun.

I agree looks like a different planet outside.
Here on the Ventura/Los Angeles county line its pretty dim and
eerie

But, careful observers will note the there will be thousands of images of the eclipse on the ground...the light through trees for example, anything light going through anything will get focussed. I don't recall what this effect is called, but it is dazzling. I saw focussed examples inside and out. On my window sills through houseplants - well they innumerable. I recall it was about as neat as the stars out, the purple sky which does not look real and the birds going nuts. Enjoy!!!
Best wishes,
Eric
<< <i>I see a black spot on the sun in the pic. Is that a planet? Venus? Mars? >>
I believe that is a sunspot. The only plants it could be would have to be the ones between us and the sun. Mars is "behind" us. Mercury is making a transit soon or just made one. Pretty scarce event.

The question about sunglasses makes me say - You can go quickly and permanently blind this way - especially during totality/near totality! Please observe as intended, or grading a coin might be the least of your problems.

Dang Magikbilly, it filtering through the oak tree on the wall about 50 feet from the wall and is in perfect focus
Good Tip, oh and the birds here don't seem to like it either

<< <i>So exactly when is it unsafe, I am in OR and nothing is different. When is it exactly insafe to look at the sun? >>
You can never look directly at the sun if you value your eyesight.

Hi Steve
Yes, looking down during an eclipse! These focused images are among the most special things I have seen in my 42 years and I have seen this and that. I am truly very elated you saw this!
Best wishes,

Pin hole trick?
All one really has to do to enjoy the eclipse was to simply look at the shadows cast by this phenomonon.

Excellent!
<< <i>You can look at the syn briefly, we have all done that, especially if playing baseball. So when is it critical not to today? >>
I remember when we had a partial eclipse pass through Detroit in the 1960's, the newspapers gave the "Don't look at it" advise and explained that if you happen to glance at a full sun, such as in your baseball example, the brightness causes your pupil to immediately contract to protect the eye.
However, if you look at a much-less-bright partial eclipse, the eye does not contract as far and as fast, and the sunlight coming from the uncovered part of the sun can enter the eye and cause damage to the retina.
I am not a scientist, nor do I play one on television. This is merely what I remember reading. Those of you who are licensed ophthalmologists may complain.
