Unfortunately I'll be on the wrong side of the planet for that - but 
there's another one on 28/Sep for me :-)

The Sun was Obscured by Clouds </PinkFloyd>.

However, my colleges and I were able to observe the event anyhow, since 
the cloud cover was not complete. I tried using a pinhole camera. My 
boss discovered that DVDs are actually very slightly transparent. But my 
suggestion was apparently the best: wrap the entrails out of a floppy 
disk and use that. Works better doubled over. Makes the Sun look like 
cola...

Been there, done that in 1999.

Yes, too stupid even for a Darwin Award.

In 1999 I used a pinhole camera. Which worked quite well.

This time it was too cloudy. I couldn't really get much of an image.

Yeah, pointing your eyes directly at the Sun is never a fantastic idea. 
Still, the number of times I've looked at the Sun with my naked eyes, I 
would think doing so with protection can't be any *worse*... The key, I 
guess, is to not stand there for eight minutes straight just staring at it.

It depends on the /protection/. DVDs are really bad protection because 
they give the /illusion/ of screening sunlight which is not the case at all.

when you look directly at the sky, you squint, you pupils contract and 
can't look at it straight for 8 minutes, anyway.

When there's an eclipse, and you'r elooking through dark sunglasses, 
floppies, DVDs, welding masks, etc, the lower level of ambient light and 
the apparent darkness of the sun through the aforementioned spectacles 
will not be enough to tell your brain to take evasive manoeuvres, so you 
actually will burn your eyes with more UV rays than you would if you 
were driving west at dusk, or skiing on a glacier in the Alps.

Presumably a decent pair of dark sunglasses will have the required UV 
protection?

Also, it seems relatively comfortable to look "near" the sun compared to 
directly at it, but wouldn't both situations result in your eyes getting 
burnt just as much?
