So i was sitting in car around 6:30 on my phone. it was dusk, just becoming light. i couldn't get off the phone quick enough as i saw this light traveling across the sky, which appeared to have come from the west coast, the ocean is a few km's away from where i live(west coast of western australia) so i quickly started phone camera(samsung galaxy s5) & filmed it for a few minutes, it traveled in easterly direction, making no noise at all. there is an airport just out of town & i hear them flying most days very clearly, however this light object made no noise at all. it disappeared into smallish cloud & came out other side, then i followed it as it moved into more cloud cover & never came out other side as i waited to see it. strange. i copied video from phone to laptop, it is raw & completely unedited.
