Bright pink coloured light travelling quickly east to west on a slightly upward trajectory over Ottawa River.My wife & I witnessed a bright pink light that moved very quickly across the sky from east to west tonight. We were travelling in our car, & both noticed it immediately as it crossed in the distance (unsure how far) from left to right in front of us. What caught our attention was not only the light (pink but slightly iridescent as well) but the movement on slight trajectory upwards before veering up and away on an impossible angel before disappearing. We were just about to crest a hill in a dark area slightly north east of the City of Pembroke. We were coming from the Province of Quebec & had just crossed the first of three bridges that span the Ottawa River. The island we were on is known as Morrison's Island & the light may have been out over the next stretch of river. When it veered away it was in a direction away from the city (north west). We didnt say anything to each other until it was gone. My wife noticed me leaning ahead as she drove and watched as well. She then asked if I had just seen what she had. There were no other possible light sources, reflections etc. There was another car ahead of us. They must have seen it as well.
