    Default Moonbows! Well, kind of....

    Ok, so they're not really moonbows, they are just an effect produced by refraction through hexagonal ice crystals in cirrus clouds, also known as an Icebow.

    Alright, hands up, WG looked it up. They looked cool though.

    Cool photos. Did you or WG take them?

    I think they may also be called 'glories'. There is one on this link: New Zealand, Australian and South West Pacific Weather and 7-day rain and wind forecasts

    I took the actual pics, but WG was doing a bit of research on them and found out they weren't moonbows after all. Looked better in the sky!

    I've seen quite a lot of them over the years. Shame the photos don't show them in their full glory, but that's often the way with cameras. I've seen colours in clouds during the daytime, too - more so with my sunglasses on, and it looked irridescent. The colours weren't so apparent without my sunglasses but they were still there, so it wasn't something caused by the specs.

    Nice photos ... I've never actually thought to take pics of them before, as where we come from in the US they are quite common in the late fall and winter.

    I imagine with the milder weather, they are more uncommon here, or am I incorrect? I seem to remember them being less common when I lived in Connecticut than when I lived in NH.

    On a related note, how far south do you need to travel to see the Aurora Australis?

    I love effects like this. A while ago, I read about all kinds of them, including glories. I'm not sure of the info source though. Wikipedia has a list: Category:Atmospheric optical phenomena

    I also found this site: Atmospheric optics: Ice crystal halos

    Here's another: Atmospheric Optics

    You can see the Current Auroral Oval at SpaceWeather.com. Scroll down the page, look on the left, you'll find it. Lots of other info at this site.
