  Parhelic Circle - High Sun
 




 
The parhelic circle shrinks in size as the sun climbs higher.

At left Grant Goodge imaged halos in Asheville, North Carolina when the sun was about 63° high. The parhelic circle is only slightly larger than a 22° halo producing a figure '8' shape in the sky

At top Damien Hutsemekers caught the sun at the European Southern Observatory, La Silla, Chile when it was 79° high . The parhelic circle is still centered on the zenith and passes through the sun but is a mere 11° in radius.
