Contrail Shadow, Corona and Tangent Arc

A knotted contrail casts a distinctive shadow on the cloud layer below.

The regular size of droplets in the lower cloud give two distinct rings to the corona plus fragments of further rings.

As the lower cloud drifted past it revealed a portion of upper tangent arc in a thin layer of cirrus higher up.
