SU0513 : Cloud or con trail, Cranborne, Dorset In a letter to the Bournemouth Echo (28 Mar 2009) an eye witness to what must have been the same cloud formation reported seeing its creation at 3 pm over Win Green near Shaftesbury on the same day that Clive photographed it over Cranborne.
The eye witness records that it was created by a high flying jet aircraft similar to a Hawk trainer which flew 3 distinct concentric circles to create this formation with its "con - trail". The writer then watched it drift at about 10 mph in a NW direction towards Blandford, which would put its general course towards Cranborne one might suppose. The writer goes on to speculate that it may have been the same circular cloud formation that was photographed over Parkstone near Poole that appeared as a photo in the Bournemouth Echo on the 25 Mar 2009 - the day after!
