Is here another fake sun?

[gallery link="file" columns="5"]

A couple of days ago I made a post about the fake sun, showing the excellent photos of Julie Bronson and drawing by Giovanni Cassini. This reminded Mika Aho of his photos of similar looking effect that he took on 19 May 2008 in Korpilahti, Finland. The two photos are shown above and they were shot with an old cell phone camera, which explains the slightly less than optimal quality. The sun is behind the edge of dark Stratocumulus cloud and the fake sun candidate is seen below the sun, with short and fainter extension of pillar further down. The crystal precipitation from the cloud is not visible.

Now it looks like there may be a circular fake sun image of the sun under the cloud edge, but it is not very bright. The cloud edge is actually much brighter.  By strict definition one could say that a genuine fake sun should be so bright that one would take it for a real sun, but of course there is a continuum of intensities, and putting an arbitrary line somewhere along the range is not very fruitful. So, with some reservations due to the images quality, I might say that probably we are looking here at a faint version of a fake sun. In any case it is good that people have started looking for this, be it old photos or fresh displays in the sky.
