Parhelic Circle on April 26th, 2004
On April 26th, 2004 a 22° halo, a circumscribed halo, a supralateral arc and the parhelic circle showing reddish diffraction fringes were visible at Trier. An early-morning circumzenith arc was rather faint, and as there were no parhelia, the whole display was probably mostly formed by columnar crystals.
