Hey guys! On 3rd July, ~00:10 AM +10:00 GMT I have been watching night sky. Then suddenly, under Arcturus (no idea how much below, but about 7 full moons in a row below it) I saw a dim star which was never there. In a matter of seconds (5-10 seconds) it increased in brightness and became as bright as Arcturus. Then suddenly it exploded silently - bright-yellow ball in the center and an orange circle around it. This explosion was as big as a full moon. It lasted 1-2 seconds. Can anyone please explain me what happened? Could it be a meteor headed in my direction, but vaporized in the atmosphere?
