Plate Arcs from Japan


These pyramidal crystal halos were observed by Anthelene over Sakaiminato city in West Japan. The most interesting features of this high cloud display are the 9°, 20°and 24° plate arcs. Marko Riikonen has made a simulation with HaloPoint2.0 ( 1 ), according to him, the 20° plate arc had been photographed only once or twice in high clouds before. More of Anthelene's images can be seen on her website: http://bluemomenttime.blog89.fc2.com/blog-entry-442.html

    Thats a very nice low sun odd radius halo complex. The upper 20 deg plate arcs looks like a low sun diffuse upper tangent arc. In the image I can see faint upp 35 deg plate arcs. This is one display that should been stacked.

    Wow! Great catch! I haven't seen any good plate arcs yet.
