Early risers around the Perth metropolitan area were stunned by a bright green light filling the night sky on Wednesday morning, but what looked like Armageddon was most likely a meteor, according to a Perth Observatory staffer.

Just before 6am 6PR News director Lisa Barnes was out for her morning run near Ellenbrook when she saw the phenomenon light up the sky.

"It was so amazing to see, it lit up the whole sky, a quick flash of light and then it drew my eyes to where I was heading (...) and then it was like a ball of light and I watched it fall."

Mrs Barnes said it was much bigger and brighter than a shooting star.
