Well spotted, the arc is a supralateral section.

Thank you Hans!
The arc hitting the CZA is most probably a part of the supralateral arc, Nienke. The crepesculars are the streaks of the cirrus in which the arc is displayed.
There is also part of a halo or so, hitting the arc? And what else do I see, something like crepuscular rays?
