Yellow dot moves slowly then accelerates and disappears instantly after throwing a white flare.It was nearly sunset, and there was a really nice view in front of me, so i thought of taking a picture of it with my phone. When i opened the camera app and took the picture, i looked again at the view, and a yellow dot was moving slowly vertically across the sky. I tried taking a picture of it, but the phone couldn't get it, then it started moving really quickly, and then vanished in the skyline, tossing a white flare-like object in the sky, which directly disappeared.
