A fallstreak hole (also known as a hole punch cloud, punch hole cloud, sky punch, canal cloud, or cloud hole) – a large gap phenomenon that sometimes appear in cirrocumulus or altocumulus clouds. I captured this recently at Lawrence Hargrave Memorial Park south of Sydney while we were whale watching.
