Wednesday's halos in chronological order. To start the morning, there was a basic ringula, sauri, zykki and also a stack of 46r. While photographing them, the attention was drawn to the 120° side sun, which was visible as a lonely brightening in the clouds. I reversed the shooting direction and managed to take a small stack before the brightness faded (photos 1-2). An hour later, a moderately sharp right Sauri with a piece of the horizon ring was visible in the sky (picture 5). Stacks of barbs were found around it, which could perhaps be from alternative Lowitzes (pictures 3-4, Sun altitude 33 degrees). However, I will leave it unmarked, at least for now. The stacks also show a weak 22° upper lateral opening and a faint second arc above it, which cannot be identified with certainty (Parry, ring-shaped Lowitz, etc.). Around three in the afternoon, a momentary 23° parhelia was still visible in the clouds (picture 8). 18° parhelia were also found in the quickly taken stack (pictures 6-7). There is also a reference to coughing, but there may also be arte born from strong coughing.

Näissä siun haviksissa on aina sellaista syvää intohimoa aiheeseen ja tarkkasilmäisyyttä, että ei voi kun monttu auki kunnioituksella katsella
