Rare cavum cloud hole observed over Połańce, Poland

A photograph taken near the village of Połańce in Poland shows an oval-shaped hole in a cloud layer, surrounded by sharp cloud edges and faint, radiating streaks. The phenomenon, identified as a cavum or hole‑punch cloud, forms when supercooled water droplets in a cloud suddenly freeze, often triggered by disturbances such as an aircraft passing through, creating a clear cavity as surrounding droplets evaporate.

Cavums are uncommon atmospheric events and attract interest from photographers and meteorology enthusiasts. The occurrence over Połańce adds another documented example of this natural but striking cloud formation.
