Morning 22 Degree Haloes

This 22 degree halo showed a reasonable amount of colour and lasted for several minutes.

20 minutes later and the halo has gone leaving just the upper tangent arc.

The tangent arc is quite colourful compared to the earlier 22 degree halo.

With the sun at an altitude of 54 degrees the curvature of the upper tangent is now very similar to the 22 degree halo.
