Yesterday evening( ~8:30pm local) I was photographing the Moon and sunset, when some bright spot apeared roughly 85° above the horizon. It was the first star to see, but suddenly (after 3 minutes of appearence) it fainted and then disappeared. There were some dots after dissapearence, which left after a few seconds too.
Now my questions are:
Is it possible that this was indeed a Supernova (it was even brighter than the moon), with some lighted gas from the Star
or was it a meteor coming in completely straight? (would not be a good explanation, because of the relative long visible time)
I know that the probability of such an event inside the milky way is like 20 +- 8 per millennium, but there is one
It could be something completly different, but I can't imagine a thing at the time.
