Without zooming in I'd say a plane that wasn't high enough to leave a contrail with the sun bouncing off it. I've seen similar ones to that
before. It could still be climbing out from an airport, or descending into one. It doesn't have to be a propeller plane, just one that isn't in
the right conditions to leave a contrail, in fact from it's size it's a jet.
