No clouds, light breeze. Transparency created a small bit of distortion. Overall good viewing from our next door neighbour's yard - they have no trees!
Cook was a low-rimmed crater. There was a small crater on its south rim and ridges to the NW. The NE and East rim seemed more shallow than the western rim.
