Driving on the highway ns 104 w i noticed this in the sky. it wasn't a jetstream and stayed basically stationary or moving very slowly. it was in my view for 15 minutes until i took an exit which made its location unviewable to me. there was someone else pulled over photographing it. the colour almost looked holographic. adjusting the colour of the photos it looks like it has an outline, the stream didn't change length. it was slowly shrinking or fading before i lost sight of it.
