I was traveling north on I-94 at approx 6;15-6:30PM CST around the Portage/Baraboo area when I noticed 3 extremely bright orange lights in the north/northwest sky roughtly 30 degrees above the horizon. At first they looked like planes in a line on approach for landing or possibly in a triangle shape they were quite a ways away(i would guess 10-20 miles out on the horizon) so it was hard to tell. Then they all appeared to drop rapidly then stopped and then they just disappeared.A couple of minutes later a line of bright orange lights appeared again just to the northwest of where i saw the previous lights they looked like a long wing with a large bright orange light at each end and in one the middle with 2-4 smaller orange lights in between the end and middle on each side. It moved soemwhat then dropped rapidly like the lights before and then just disappeared - all at once, there was no slow fading or one at a time -it was like they were all turned off.I have lived around an airport all of my life and am very familiar with nav lights etc, these were not like anything i have ever seen before. They were a bright orange steady burning - no pulsating or flashing. And definitely not typical plane lights - there was a plane that appearded to be flying above them traveling to the north wthat was not effected or did not appear to close to them. I was freaked out a little - it reminded me right away of some of the ufo type videos i have seen. I called my finance right after and described the whole ordeal to her.
