Halos imaged

A colourful halo surrounds the sun, likely a 22°. However, the previous day had seen pyramidal crystal halos over Norway and they appear here too. Close to the sun there is a 9° halo and the diffuse brightness beyond the outer ring is suggestive of a 24° halo. There is possibly also a lower 24° plate arc from partially oriented pyramidal crystals.
A faint parhelic circle crosses the sun and on the circle, well
beyond the 22° halo, are two sundogs.
The halos appear non circular because they are off-centre in this wide
angle view.
My thanks to Marko Riikonen for the interpretation.
