Southern Hemisphere star trails

Unlike my other star trail photo from Portezuelo, Chile, this one is on a moonless night. This represents 46 minutes of the Earth's rotation.  Portezuelo is at the bottom of the photo, and the southern celestial pole is off the top right corner of the photo. Just above center, you can see two meteors streaking across the sky (one of which is accentuated by some unknown green dot...I saw the meteors and there were no green bursts). The dotted lines are from 2 airplanes that crossed my path as they were leaving the Concepcion, Chile airport, which is about 2 hours west of where I was.  Each exposure was 2 minutes long, at 18mm, ISO @ 1600, f/7.1.
