I was driving east on the 210 freeway in Rancho Cucamonga. I was on the off ramp at Milliken approaching the stoplight when I saw the object out of my windshield. I've never seen anything like it. The best way I could describe it is it looked like a ball of white fire. I thought maybe a meteor? I have no astronomy experience but would live to know what this was if you confirm. All I know is that it was very cool to see! Thanks!
