Here is in detail the supralateral arc sticked to the circumzenithal arc (which appear in the Quimper's sky on December 3, 2003).
For a long time, I believed that the supralateral arc was the 46 degrees halo. Indeed, the 46 degrees halo touch the circumzenithal arc when the Sun is at an elevation of about 22 degrees. In this case, the Sun was at 18 degrees of elevation. The 46 degrees halo was just 1 degrees from the circumzenithal arc. Son it's difficult to decide.
What makes me believe that it is a supralateral arc is that the upper tangent arc is very bright and the 22 degrees halo rather inconspicuous, however the supralateral arc and the upper tangent arc are linked and doesn't appear alone. While the 22 degrees halo is quite hard to see when a supralateral arc is visible.
To help you to decide by yourself, read thoses pages describing in detail the 46 degrees halo and the supralateral arcs.
