You didn't read either thread that I linked to, did you? As andrewas said, you don't hold the pinhole camera up to your eye.

Uh sorry ! no i didnt read any of these threads because your post didnt show up on my mobile phone (bad connection i guess)... I just saw it now.

I might try this, but since i have protective glasses i'm not sure i will do it.

And reading that post again now, it sounds a bit more snarky than I would normally be comfortable with. Sorry. Glad you got sorted out. Enjoy your eclipse. I've got to wait until August 2017 to see one in this part of the world. The path of totality for that one lies about 1000 km south of me. I intend to drive down to see it.

Forgive me, Science, for I have derped ...

Just looked at the weather forecast for friday, will be cloudy, so we will need lots of luck here ... :P

I also noticed that it will be a new moon that day ... so I felt happy, because "it will at least be dark enough to see it" ... then I felt dumb, because "does not matter, it will be daytime anyway" ... then I felt really dumb ...

All in the short span of two and a half second ... :(

don't sweat it, I think we all derped in such a fashion at some point. I personally have been on of the many, MANY people who have on several occasions referred to our Moon as Mun, and Mars as Duna. I remember once looking at a picture of Mars and going "hey, where's the large polar caps?" before feeling very silly.

I may have also at one point briefly looked for Minmus in the sky, but I may be remembering that incorrectly.

The dumbest thing is still to come. It is always a new moon during a solar eclipse. And when I say always I do mean ALWAYS. The moon slides between the sun and the earth, from earth you'll be looking at the unlit side. Also known as a new moon.

Just wondering here, how dangerous is it to look at the sun during an eclipse?

People always say don't look at the sun, but let's be honest, you can for a few seconds before the brightness is to much.

Is watching an eclipse the same as this? The only thing I can think of is that since it will get darker during the eclipse maybe your pupil expands or whatever it does when it gets dark to let more light in, and that could possible damage your eye more.

Ok, but does this include just looking at it with the naked eye? This post seems to specify not looking at it through various damaging lenses and stuff

Yes. Your eye is a lense too and though the surface area is limited, when focussed it is enough to hurt whatever lies beyond. That is why looking at the sun hurts - to prevent you from doing it too often or long. Your eyes are sensitive instruments and the sun is a ball of blazing fury.

It depends.

100% totality - safe to look using regular pair of eyes. :)

It can even be watched using a small telescope (small objective diameter, large magnification) without filters, but that's kind of playing with luck. Unless you know exactly for how long the totality lasts at your place (down to a second), you can't be sure for how long you can watch it. What if you don't know, and suddenly the Sun starts peeking from Moon's limb? I'd do it if I was absolutely sure what I was doing, otherwise not.

The reward could be this.

Corona, chromosphere and prominences aren't shiny. In fact they are very dim. I think even full Moon has greater magnitude.

diamond ring - glancing using naked eyes is ok, staring is absolutely not. Using a telescope - absolutely not unless shielded, just like any other phase of eclipse. Photosphere is visible.

Baily's beads - I wouldn't even glance. Glancing with squinting, yes, but it's also playing with luck, as the photosphere is becoming increasingly visible. It's like diamond ring, but several of them therefore more danger. It's like looking at arc welding. It doesn't hurt because the overall retina exposure is low, but it will cause damage because tiny parts of retina get bombarded with Sun's fury. :)

other phases - not even squinting and glancing. For all intents and purposes, it's like the Sun isn't eclipsed at all. Only proper filters can be used.

Yes. The sun is much more dangerous during an eclipse, because its possible to look at it directly with dilated pupils, and then totality ends and your eyes are damaged before they can look away. Under normal circumstances, looking close to the sun hurts and your pupils are contracted, so while its still not a good idea its much harder to do permanent damage. Of course, this isn't a total eclipse for most of us, but it may still be dim enough to give the impression the sun is safe to look at.

hi, how does the media cope with this astronomical phenomenon in your country? In Germany I saw one paper saying "Oh my god, the power drain could be to much" the other featured an interview with an eye specialist, like: "don't look you'll turn to a salt figure damage your retina and if you come to me afterwards, I'll be like 'told ya'. but with some luck it's cloudy and rainy anyway..."

I don't even want to know what the BILD wrote about this or if they just put the headline on their weekend edition: "Sun darkened unforeseeably, Salafist's or Russia?"

what the actual !? can we have some professional journalism in our times? why are newspapers THaT stupid and useless?

argh, sorry for that rant. enjoy your eclipse with the proper eye protection of your choice. don't let your teacher or boss stop you from watching it!

There is an interesting crowdfunding campaign going on: https://www.indiegogo.com/projects/bloon-360view-of-a-total-solar-eclipse-from-space

These guys are planning to fly (well, presumably are currently flying) a high altitude balloon with a 360 degree camera to capture high resolution video of the entire event from beyond the stratosphere. No clouds, no atmospheric scattering in the way. Footage like this has never been recorded before, especially not of an equinox eclipse such as this one.

The campaign doesn't really say how or where they plan to release/distribute it, but from the current looks of it, they'll probably be forced to monetize it (since the campaign is going to fall far short of its goal).

Quite foggy in northern germany. Only saw it for a couple of minutes through the clouds, but still rly cool :)

edit: ofcourse only partial

Exactly the same in SW England, high & low cloud with occasional breaks. The seagulls went noisily crazy though...
