Shape: Changing
Duration:4 minutes
Three minute video shows an extremely large cube shaped object that appears to be rotating with a variable flash rate.

I filed a report on this sighting earlier. I had reported that the object resembled a very large Mylar solar sail. Since then, I had time to review my 3 minutes of video with some software that allows me to slow down the frame rate. I am filing an image I’ve been able to copy from a screenshot that shows a monochrome cube shaped object in a large checked pattern. I observed this object for 3 minutes as it appeared to rotate and flash extremely brightly randomly. The period between flashes were as short as 3 seconds and as long as 20 seconds. I counted sixteen flashes with two periods repeating themselves; 4.11 seconds, 14.82 seconds.
