Arcs and halos

I saw these arcs and halos around the Sun on March 2. The halo is pretty common given the right type of clouds, but the Upper Tangential Arc is a little more rare (the arc heading right off the top of the halo). This image was taken with my Canon A75 with wide angle adaptor, the lens was set to 5mm and the adaptor would have made that about 3.3mm. THe exposure was 1/1600 sec at f/5.
