About 9:15 tonight Friday 13th I spotted a bright bright light traveling towards me(out the front of my house in Oakden (Adelaide) traveling north(i thought it was a plane really close, by the size of the light and the brightness,but I could not hear a plane,I did not look away because the light reminded me of a planets light and there was no flashing wich all plans have on their wings,but was traveling at plane speed tho and way to slow for a satellite,it then dimmed by about 80% of it's brightest then I was intrigued,then I thought oh the plane has just changed direction,the object was now about 80% dimmer and 80% smaller in size it was now traveling west(still no flashing like a plane) for a few seconds in that time in a few seconds got brighter and dimmer,changed directions again travelling south now got slightly dimmer no change in size then within a few seconds dimmed and disappeared,so whatever it was was traveling to antartica? I probly live 50 or 60 kilometers from Adelaide airport,what could have it been? Got so close, to be a bright bright light that of a plain coming directly at you about to fly overhead,not hear any plain noises no flashing of wing lights the massive changes in brightness and size and then disappear traveling south? Not east or west towards Victoria or wa or something? Strange freaked me out a little someone please explain!
