Witness Account

Three individuals, 6:45 pm, Sisson Park, Mt Shasta. We spotted what looked like a star but was moving erratically. I began to record and the "star" quickly moved to the left and changed colors. On closer inspection, we noticed the object was square, with a pulsating purple light in the center. The object continued to move and change colors for at least 10 minutes. I have a video.
