Another afternoon with a mixture of halo effects in different patches of cirrus.
This started with a weak 22 degree halo in some rather mottled cirrus, never quite making a full circle.
|
|
|
This was followed by a very bright and colourful sundog with a distinct white tail.
|
|
|
|
Then a colourful upper tangent arc developed, with part of the 22 degree halo curving down to the right.
|
|
The show finished with this faint circumzenithal arc.
