The image show the dark silhouette of a tree and rooftops at bottom, with the Sun right above the tree. Sundogs are visible left and right of the moon, a faint halo can be seen and a concave arc at top in the image. This is the upper tangent arc. The lower half of the sky is brownish from dust in the sky.
Faint #halo, #sundogs and upper tangent #arc around the #Sun through Saharan dust right now.
