13 seperate lights in a low to high formation at approximately 200 ft to 1000 above sea level. Slow moving and hoovering near Resch Park. No sound and moving up and down in motion with lights eventually disappering. If there had been a very high rise building it would have ressembled outline lights of work area. Bright to dark orange in color. Also, could have been similar to hot air balloons except the formation was more strategic than random.
