Very huge mass with black figured markings no outer rimWhile driving south on 101st towards Lowes a huge mass was very visible on my right side in view, it was a huge mass in a circular pattern but no outer rim could be defined it was made up of dark black figues mostly like a L or similar. It was motionless for a few seconds then dropped about 1 foot then back up, then dropped straight down very very fast. everything moved at the same time. I have reported this to mufon. I served my car at the end because I have never ever seen anything so HUGE in the air, it was basically right there.
