Hole punch cloud 14 December 2010 in Tampere
I went to check the diamond dust even though it was cloudy. There was nothing, as expected. I was reporting in the phone to Luomanen the situation when hole punch cloud caught my attention. The Ac was probably the slowest moving I have ever seen and there was plenty of time to photograph this. Much different from the other hole puch a few days earlier in Hervanta, which moved and changed really fast. I have never seen hole punch clouds before and now two cases in the row!
