Visibility II / V
Such an attention-grabbing cloud brightening raised the suspicion of a possible cloud arc stump. It looked very unusual in the otherwise evenly toned cloud front. The sky was completely clear on the sunny side, so there was no ray of light caused by shading.
A clearly lighter spot in the front stood out even when the clouds were lower on the horizon. In these pictures, the case emerges perhaps most clearly. The distance from the center of one's own shadow to the point of lightening remained approximately 40 degrees during the time I was monitoring the situation.
