Atmospheric Optics is the fancy name for light and colour in the atmosphere, such as rainbows, halos, shadows, and mirages. This page will try and explain in simple terms how these beautiful phenomena occur, and where and when to look for them. Many wonderful things go unnoticed every day simply from not knowing where to look. Along the way this site will branch out to related fields such as weather phenomena, and light outside the atmosphere - the heavens above
Parhelia or sundogs as they are more commonly known are caused by ice crystals in the atmosphere. They lie on the 22 degree halo either side of the sun.

its a spec, a tiny water droplet, maybe spital, it looks bigger on the lens due to the distance between the glass and media (film plane or sensor)

Now, here it is cropped up-close:
Again, I am not claiming this to be anything in particular, but I do find it a little bit odd. I'm sure we'll never know....but maybe I'll look a bit more closely at my pictures from now on.
Right now, a mini-moon is probably orbiting our planet. It could reveal the history of the solar system – and make some people very rich.
Computer models of asteroid orbits are showing that small space rocks a few metres across can lodge in Earth's gravitational field if they stray too close. Only a tiny fraction of them break up and hit our planet. Most orbit unseen for months or years, somewhere beyond the moon, before slipping safely and silently back into deep space. But while they remain close, they are mini-moons of Earth. Not only are they turning out to be more common than anyone thought, they could play a vital role in unravelling our solar system's secrets.
Granvik's model predicts that most captured objects drift off again, spending on average just 9 months in orbit. Perhaps the biggest surprise, however, is that such temporary mini-moons are common. "There is probably one up there right now," says Granvik.
