i was siting in the backyard on the patio at a little after 10 pm. it was summer time on a cloudless night with a full moon that was super bright that night. i wasn't using a telescope or binoculars to search the sky, just observing the night sky and relaxing. the moon was full high up in the sky. it was a pretty quiet night at that point. i noticed a light coming towards me just right of the moon. the light didn't look like it was very high up maybe 500 ft up, which is why it caught my attention. it was not moving very fast towards my direction either, slow steady. the object turned south heading in the path to cross the full moon. when it turned the light that i was observing completely disappeared but what i saw behind it sent my heart racing. i could see a visible outline of a very large aircraft? airship?. it did not look like a traditional ufo. it was being illuminated from the full moon from its surroundings but you could not visibly see the object. it wasn't invisible, more like it absorbed the light. i would not have been able to even see what i did if the object wasn't so large and low in the sky. for as slow as it was moving with its incredible size there is no way it was flying like a normal aircraft. there was no noise either, no engine noise. once it had crossed between the moon and i, it was no longer visible. the whole occurrence lasted about 1-2 min. i sat outside for awhile longer hoping something else would happen and started looking up if anyone else had any encounters that night. i did find one other person at that time who was in detroit area that posted a picture of an object that looked similar to what i had seen the night. i'm not able to locate that anymore.
