I thought it was a 'shooting star' started high and white like a star then while 'dropping' it got brighter and turned white with pale yellow and then that became like a tail to the "star ' doubling or tripling in size and brightness while turning a light then almost true green with the bright lime green around it and white/pale yellow short tail. It fell from high and left to almost straight down but slightly right. I couldn't see it after it went "behind" the hills/mountains of the desert my backyard/driveway opposes. Best thing I've ever seen in the sky!!!!!! And it all happened while on the phone with my parents in real time. I was truly quite literally speechless for several seconds!!!!!
