Moon Halo

Overblood

I only found out about this forum today but I have these photos a few months. Ever see one of these before? Very strange to look at.

Nice pics there , assuming its not camera lens glare, this is quite common ,
caused by ice crystals in the atmosphere i believe , though others on this forum would be much more knowledgeable than me .
Have you heard the saying (well its here in kerry anyway).....''far ring near rain '' ........the early signs of an approaching frontal system is often signalled by a halo around a full moon , so the further the halo from the
moon , the closer the rain (or mabye snow this week:p)

Overblood

Haha no it's definitely not lens flare! Yeah I know what these are and how they're formed, but the first time I've ever seen one is just a few months ago. Came home from work at 2am and turned around to see this huge other worldly vision, I was like "woah dude!". A very cool sight to behold. They're also called "Glorioles"!!!

And yes I've heard the old wives tales about how they are a foretelling of rain, but that doesn't really apply here in Ireland since it rains 99.999999476% of the time. :pac:

erm ....and where did you get that statistic regarding rainfall in ireland
then....

Lovely pics, i've certainly seen lots of pics of them before but don't think i've ever seen a halo before or certainly not as pronounced as that one

I have seen a ring around the moon a few times now , People i know say that it is a sign of a storm. Last time i seen it got very windy too.

Overblood

Yeah but as I mentioned earlier, it's nearly always windy or rainy here so anything can be taken to be a sign of rain or wind. If you see a brown rock on a lump of moss that means rain etc. If I was in the Sahara desert tonight and saw a moon halo, and the next day it rained buckets onto the dunes, then I would give the tale some credence.

Maybe it's proven scientific fact though, I don't know. Must google it actually.

The halo effect is caused by the 10/15 second long exposure, take the same scene at 1/10 and it'll be your regular moon

Eh, the halo effect is caused by ice crystals in the upper atmosphere, not 15 second long exposures on cameras. You obviously don't have a clue. Here: http://en.wikipedia.org/wiki/Halo_(optical_phenomenon)

The reason I took a long exposure is because it was pretty dark.

You see, at night it gets dark. You can read about the night here if you don't have a clue about that either: http://en.wikipedia.org/wiki/Night

Night or nighttime is the period of time when the sun is below the horizon.

Wow. Sun goes below.... wow. Unbelievable.

1/10 of a second and the whole picture would have been pitch black.

Oh jesus what are you doing.

What are you trying to say. I don't get you at all.

Do you understand photography at all?

That chart is for taking photos of JUST the moon. Like this (my pic by the way:cool:):



The moon is pretty much as bright as the sun as far as the camera's concerned, so of course a fast shutter speed is needed. But I wasnt taking a photo of just the moon. I was taking a photo of a dark landscape of which the moon played a small part. It was mostly DARK and mostly NOT MOON. So I'm not going to use that fecking moon chart to take a picture of a load of trees and a car am I?

I might print that chart out and use it as bog roll actually.

LOL! Has to be the most sarcastic reply on Boards ever!!!


Nice Pics BTW

Overblood

I saw another one of these last night but I didn't have my camera with me!

By the way soccerc, how was I able to see the moon halo last night if I didn't have my camera with me? According to yourself they only appear when you take 15 second exposures on cameras, like some sort of magic trick.

Its out again tonight looks class but its quite hard to photograph
