Something flew through my star trail picture

Tonight after dark I set my camera on the tripod outside my house and pointed it toward the sky. I started it clicking away and went inside to wash dishes and stay warm. After the battery died and I downloaded the images and stacked them, I was surprised to see the streak of light that starts at the lower left and goes to the right and up at a slight angle. I don’t think its a plane since their lights usually blink. Maybe a shooting star, anyway I missed it while I was washing dishes…
