There's so much variety in cirrus clouds - streaks, sheets, curls, hooks, waves, and random patterns. These were lit by a low sun in mid-afternoon.

Cold sky
It was chilly at ground level, but between 16,500 and 45,000 feet it was even chillier. In the morning a few isolated patches of cirrus floated about, but this is a larger area formed of two types of cirrus: at the top of the picture, streaky cirrostratus, a milky veil at about 30,000 feet; at the bottom of the picture, the bobbly appearance of cirrocumulus, which is higher.
At sunset, there was a layer of altocumulus overhead, larger bobbles than the cirrocumulus, at a lower altitude.
Lower still, a few cumulus caught the colours of the sunset as they faded away.

Cross winds
The cirrus streak is being swept along by the jet stream - high speed winds at about 30,000 feet.The cumulus, lower down, is moving at a different speed, and in a different direction.
