A blinking or pulsating light appeared in the East by the horizon, i thought it was a shooting star but then it kept going. Blinking as it streaked across the sky. It went from the horizon in the West to the horizon in the East and continued on to the East. It was impressive in that it did this remarkably fast. I’m not familiar with calculating air speed but it must have been in an order of magnitude around 100x that of a plane. In fact, the speed is what was remarkable about this incident.
