Never trusted you anyway.

The phone comments are just silly. The sensor would be overloaded, and the screen wouldn't resolve any image. It wouldn't be dangerous. Just pointless.

There are plenty of safe ways to view tomorrow's eclipse that don't cost any money at all and won't do you any damage.

Google them.

I'm not attacking you, but it has been published all week, warning people about using their smart phone to line up shots, mainly in regards to selfies, so found it a little odd that you suggested it, with out explaining further, especially after your comments re viewing through a telescope.

And on that comment, i'll put this little arguement between our selves aside as well.

Wait for the 6.01 news and see it in HD.

How do people think this?

Camera sensors work completely different to eyes and also cannot be damaged by light.

Enda do us a favour go stare at the sun and report back. Too early for this pointless bitchiness.

To be fair to Enda, he's making a valid point.

Don't look directly at the sun. Under no circumstances should anyone do this.

So it might be worth a shot so

when are the irish sending a man to the sun??

But obviously…

I was asking about the resilience or sensitivity of the human eye, specifically the question of instant blindness, as a matter of interest. Nobody is advocating staring at the sun through a telescope.

It's no different to discussing mortality and the physics of high-speed car collisions. Morbid/ scientific curiosity. It doesn't mean you're encouraging dangerous behaviour.

Well if you're just looking at the screen it will be fine but you'll most likely just get white out as it will be too bright.

That has no relevance to fact-based discussions on a forum where facts are often taken to be a matter of opinion, and posters don't like to be told that they're wrong. It's OK to be wrong about a lot of things, where the only damage likely as a result of the 'facts as a matter of opinion' mentality is that the poster looks a bit foolish to those who know the topic. This could be more serious though, for somebody reading the discussion, and might take a chance based on what they read.

That's why my post appeared snappy, and I don't apologize for it.

Here.

Tried and trusted methods, from those who really do know what they're talking about.

Have you ever tried using a magnifying glass to burn a piece of paper as a kid?

The magnifying glass is no more than a lens, binoculars/telescopes are the same albeit even more refined. Cooking the back of your retina's is not all that smart.

If people still want to take that risk to "see what happens" consider making a donation to NCBI.ie today while you can still see.

Would a pair of sunglasses be safe to look? Is it at exactly 9:30? I always miss out on these things so I'm determined to see this eclipse

Muahahaha · 19-03-2015 12:16PM

It begins at 8.24am in Dublin but the maximum eclipse will be at 9.29am with all activity over an hour later.

Cant wait, I finally get to see the dark side of the moon

Oh thanks for that. For someone who is so into space and the stars etc, I've never seen anything bar the ISS 2 years ago so I'm really excited

Generic Dreadhead · 19-03-2015 12:19PM

This is for the Eclipse of the Sun! It's Coming back around again! Huh! This is for the Eclipse of the Sun!

Don't worry you won't see it .

Guaranteed cloud cover apparently.

Depends on cloud density. A bit hazy = no problem.

No!! Sunglasses will not provide adequate protection for your eyesight as we will not have totality here in Ireland.

If you're determined to see it with a pair of sunglasses, you could be seeing the outline of the sun permanently.

Even with totality, sun glasses will not provide adequate protection. On two counts, cant remember the name of the term right now, 'something' beads, or a diamond ring effect, where during totality, glimpses of the sun passes through the mountains on the moons, the second reason is when the sun starts to reappear the UV light from it will become intense again, causing damage regardless of the strength of the sunglasses.

The ONLY safe way I know of looking at it directly are special glasses supplied by some of the astronomy societies/groups. Even then I would be extremely cautious that you put them on before looking up, they do NOT come off untill you look down again, and be very cautious re damage or scratches, as any of these can let the damaging UV light through. Its just not worth permanently damaging you sight for the sake of a second or two.

During the last eclipse 15 yrs ago I am pretty sure that some newspaper gave away free Eclipse glasses. Not 100% sure mind, but I did have a pair.

when does the sun block out the moon ?

Never. This is due to the Sun always being further away from the Earth than the moon. We are actually lucky to live in the time that we do when it comes to observing solar eclipses as the sun is 400 times bigger than the moon but also 400 times further away. That's why when the Moon moves in front of the Sun during a solar eclipse they match up perfectly as both appear the same size to the observer here on Earth. In thousands of years to come they will no longer match up perfectly as the moon is moving ever so slightly further away from the Earth so during a lunar transit of the moon across the Sun in a hundred thousand years from now for example, a small portion of the sun will still be visible as the moon passes.

Where was the one 5 years ago over the UK and Ireland? What was the coverage, dont remember it at all.
