While sitting in my vehicle, out of the corner of my eye, I noticed an object moving across the sky, nothing unusual. So I did not pay it much attention. A few seconds later, I looked out again the light was still moving. I noticed how quickly it was traveling. I rolled down the window and watched it for a few minutes, nothing real extraordinary. At this time I exited my car, and watched it fly for about 30 more seconds, when the object started flashing very quickly, exactly like a strobe light. THE OBJECT UNMISTAKEBLY WAS FLASHING AT A FAST PACE AND HAD STOPPED MOVING ACCROSS THE SKY. After flashing for about 30 to 60 seconds the light disappeared. Leaving me confused and exited.
