It's another persistent contrail, at a higher altitude. The plane was likely climbing through the saturated layer, got to the outer bounds and stopped
leaving a trail when they hit dryer air. You can tell the winds are different towards the left side - the contrail's being blown about in a way it's
not on the right side.
eta: while there's not enough cloud cover shown in the shot to really be sure, from what I can see, you've got cirrus and cirrocumulus showing. That's
telling you something. You have cold dry air on top riding over a warm wet lower layer. The weather is going to probably deteriorate over the next 24
hours and you'll get a good rain, maybe thunderstorms depending on the surface temps.
Unless the cold front comes in with a strong wind and blows the underlying warm wet air away before they start mixing.
