Visibility IV / V
The last day of Haloh April served a few momentary halo rarities. The halos were visible from the morning, but at first the mood was quite sluggish. Over the afternoon, 22ys, 46r, and 46as brightened, but the lower clouds effectively hampered observation. At 16:30, Parry, who stood out with his naked eyes, appeared on the ground (Figures 1-3). However, it soon weakened and was left almost immediately behind the clouds. I then photographed the stack away from the Sun, with the idea of getting an observation from a poorly separated horizon ring at 120 ° saur. It went undetected this time, instead a piece of the lower solar arc grabbed the images (Figures 4-5). An animation of the stacked stacks of 15 images (Figure 6) shows that the arc stays in place as the clouds move. After these pictures, the sky went into the cloud and the show was over.
