I photographed these 2 aerial oddities today,
09/10/08, high in the sky above Puttenham Common, Surrey, UK.
Above image is enlarged but otherwise untouched; below is the same shot yet shown in negative mode.
Nothing unusual was visible at the time of shooting; this was 1 of 20 random shots that I took as an
experiment to see whether I could obtain any sort of phenomena that was otherwise invisible to the naked eye.
The shots taken immediately before and after this showed nothing out of the ordinary.
