Aeroplane contrail stitched from 9 images taken within a period of 18 seconds over an arc of sky of approx. 60°. Flight direction from right to left. The contrail comprises two features (a) the rapidly rotating, thus increasingly contorted, almost pure white segments and (b) a background of rising and rotating wisps just above. Only at 100% resolution barely visible: the most recent wisps on the left and the oldest, almost completely evaporated contortions at right.
