Looked like the moon looks behind a cloud but moving

Saw a huge moving light cruising along from the northwest sky moving east. It looked like the moon looks when it's behind a cloud but the entire thing moved along with the cloud or whatever was obscuring it. It seemed close to the ground....much closer than any planes or helicopters fly. We hopped in our car to get a better look but it was gone. Alot of stars out, not much light pollution here. I watch the night sky alot & have never seen anything like this in my 52 years. My husband was dumbfounded too.
