It appeared just above the Star Market on Boylston street in Boston. We live 4 floors up across the street. My boyfriend and I witnessed a bright light zooming across our eyes that at first I thought was a shooting star and quickly realized it had to have been something else because of the bright turquoise color. After a few seconds zooming by - it disappeared / vanished.
