2 Groups of Stationary Fire Lines lasting over an hourAt 1845 hrs 2 groups of light were seen in the sky for approx 1 hr 15 min. One group northerly from our position at the Kirkuk Regional Air Base located in Iraq had 3 small fire lines, the other approx south by south west had 1 larger fire line. The two groups of fire lines were oriented in different directions. The fire lines appeared to come from the sky and were bright enough to penetrate the light clouds that passed by. The lines grew steadily brighter and then receded, but never appeared to change distance, heading, or other appearence. In the vicinity of Kirkuk their are oil refineries and other plants that have large external flames, however this phenomena has never been experienced here. It did not appear to be miisles, rockets, aircraft, or other such military weaponry or hardware known.
