Solid Black BlobWhat was seen in the dusk sky was a huge completely black solid blob. It was moving across the sky slowly. The 3 of us that were upstairs at the time seen it. When I ran downstairs to get others to see it and to grab the camera, it was gone. It was seen for only 1 minute. It took me 30 to 45 seconds to run down the stairs and for someone to go looking for it. There were no lights on it. There was no sound with it.
