Noctilucent Clouds

A selection of pictures here of Noctilucent Clouds over Perth. The rare clouds are the highest clouds that form in the atmosphere, and appear for a short window each year between late May to late July. If the clouds have formed, they will only appear once the sun is 15 degrees below the horizon after sunset or before dawn.

2013 Was a good year for the clouds forming, and here are some photos taken over a few nights.

Full collections of pictures can be seen here.
