Black line in sky running from horizon to top of sky.
I was driving northbound on I-75 just south of exit 46 in Hilsbourough County, FL. It was a mostly sunny day with a few clouds scattered throughout the sky. At the listed time I looked out the left side through my driver's door window. At this point I saw what apeared to be a deep blue or black line running from the horizon to somewhere in the sky above the my car. This line was about the width of a full moon. It appeared to run from the west horizon to the top of the sky, wich was out of my view. I thought it was something on my glass so I moved forward and backward to see if it moved. I then rolled my window down to confirm that it wasn't on my window. I also noticed that this line was above the clouds that were in the sky. It looked like someone had taken an pencil eraser and "erased" the light blue part of the sky where the line was. Where the line was looked dark, like I wasn't looking through the atmosphere, but straight into space. The edges of this "black line" weren't crisp. They faded to the light blue that was on both sides of the line. After about a minute the line slowly faded away and the sky turned to its normal color in that area. I have never seen anything like this and have no idea what it was.
