A cold but bright start which then changed into some hazy sunshine, Two PWs and a K13 active for most of the day (until one PW got a main wheel puncture). The PWs were launching to 1900' and there was some reduced sink and zeroes in places with indications of local wave. The K21 was flying and Ventus RB had its first outing after its summer holiday in Membury.
Here is a picture of what seemed like a lenticular over AD, it gave some reduced sink but not really any lift.
