Traveling on freeway approx. 5:45am, about 72 degrees, sunroof ajar (tilted approx 1") but not fully opened. Sudden loud explosion of sunroof glass. First thought projectile, possibly bullet. Upon stopping and inspecting, no foreign object in car and very little glass. Appears most of the glass exploded outward. In addition to shattered glass, stress cracks appear in remaining glass.
