While I was taking pix of Comet NEOWISE and with clouds that had just mover over the comet making it very hazy, I noticed a tumbling satellite so I took this pic (cropped here to contain just the satellite) at the front of the Big Dipper (pointer stars indicated here). In the 20 second shot here it had 4 brightening sequences as it tumbled. If you look carefully you can see the path of the satellite between the brighter sections.
