Yes. It seems that there is clear a 44° parhelion (multiple scattering halo e.g. parhelia of parhelia). In picture halot5.jpg you can see both supralateral arc and faint 46° halo. That parhelion is closer to sun than they are...

Heliac arc is faint, but I think it is there. I can be seen if one uses strong unsharp mask for some of those photos. In some photos there seems to be a possible upper Tape arcs (=(46°) supralateral Parry arc) too.
