This strange cloud formation was photographed near Sidney, and Twitter threads show photos taken from UVic, as well.

Ed Wiebe, Scientific Assistant at UVic explains the background on Twitter. The formation is known as a BԪַfallstreak holeBԪַ in which a large gap, usually circular, appears in cirrocumulus or altocumulus cloud.

Wiebe explains that the fallstreak hole, also known as a BԪַskypunchBԪַ is formed when the water in the centre of the cloud drops below freezing and enters a supercooled state but is not yet frozen, and begins evaporating away from a disturbance in the centre.
