Fallstreak Hole

During an evening run, a fallstreak hole forms within an altocumulus sheet. According to Wikipedia, the curious formation occurs “when the water temperature in the clouds is below freezing but the water, in a supercooled state, has not frozen yet due to the lack of ice nucleation. When ice crystals do form, a domino effect is set off due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.”
