I was taking photos this morning from Llanymynech Quarry and these went past, could it be Kelvin Helmholtz instability ?
Taken with a Nikon D500, 1/200s exp, ISO 200, f/8
thanks
Dave

Looks like it Dave, nicely captured. Saw something similar here just after 6, though rather more ragged...

thanks all for your replies. I was surprised how quick they seemed to form and then disperse, is that normal for this type of cloud ?
thanks
