Hi,
I first spotted it as a bright flash, about 60 degrees above me NE horizon. It was very bright, like a strobe, and a point source, but lasting longer than a strobe flash - it varied, from about a quarter second to a half second. It was so bright I saw it as a streak when my eyes moved - more then twice as bright as a well lit ISS pass, or venus, but not sure on magnitude. It flashed intermittently, between about 2 seconds and 15. Sometimes it was less intense. It didn't seem to be moving at first, but then it very slowly moved eastward, staying in the northern quadrant of they sky. There was no light that I could discern when it wasn't making a flash.
