It was in Chula Vista, Ca. I was studying with my sister when my mom (who was outside) noticed something outside in the sky. I walked out and there was this thing on fire far up in the sky in front of us. I think it was quiet, I don't exactly remember. But we were the only ones who spotted it. It looked like it was going down, then it burst and a trail of sparks was left behind. It suddenly got less fiery and dissapeared. It was really weird- I expected to hear about it in the news, but nobody else I've talked to has seen it. I was like 'WOW! It's a U.F.O!'- I was excited and a bit fearful. I tried to take a picture but I didn't have a camera on me :/ P.s- I'm not sure of the exact date I apologize
