How to use altitude & direction to find in the sky
The curvature of the shadow's path and the apparent rotation of the Moon's disk is due to the Earth's rotation.
During this penumbral lunar eclipse, the Earth's main shadow does not cover the Moon. As the Earth's shadow (umbra) misses the Moon during a penumbral lunar eclipse, there are no other locations on Earth where the Moon appears partially or totally eclipsed during this event. A penumbral lunar eclipse can be a bit hard to see as the shadowed part is only a little bit fainter than the rest of the Moon.
