Hi, Im from Indonesia and I was just opening my garage when I realized a very bright blue object blinking in the sky. I guarantee its only flashing blue because the color was very dark. Dark Blue light flashing in the sky. Ive done some research out of curiosity and my best answer was the Sirius star but, it was said the the Sirius star blinks multiple colors non-stop while this object/star was like blinking in and out. Blink blue in the sky, dies out, blinks again and etc for a while before it disappeared. I tried some video capturing but my smartphone's camera was too crappy to capture the blinking object. So is this a star or what? And what type of star is it? A dying one? A nebula? Perhaps extraterrestrial life? It was very bright in the sky and it was the only object/star shining.
