Oxenhope contrail vis... quite exotic when apparent! 21-08-2009

Initially a strato sky with no gaps... thus it remained until mid morning when it started to break from the west. However it must have been quite warm up there as whilst there were many jets in the upper air, they were very difficult to see owing to lack of contrailing. As mid day approached the sky opened more and a few shots were possible between the clouds... again proving much variation and some very exotic! but much heat haze and instability in the upper sky.

Jet2.com... the most common form of aerovis over here... may be of interest to someone? (c) 2009
