An upfacing infrared camera captured an object moving from screen left to right about 5 seconds after another previously posted

An infrared camera faced upwards captured an object moving from screen left to right. The four screenshots show that it seems to change shape, but it is more likely rotating as it moves left to right in the direction pointed. The third screen shot seems the best or clearest to me. This appeared about 5 seconds after another object, previously posted at NUFORC, had crossed the screen in about 4 seconds while maintaining the same appearrance throughout.
