Red light over small town of Nappannee.Unkown light source during the 4th of July firework show in Nappannee, IN. Craft emitted a dark red light. Remained still for 4 minutes and vanished. Most likely not a lantern as it had no movement and instantly vanished. Also much darker than any lanterns in the sky. Not a firework as it remained visible for 4 minutes, and showed no movement. Not a drone due to its instant vanishing. Light was stonger at times and dimmer at others with no set pattern. Later that night odd lite clouds appeared. An electric blue color as if lightning. Visible for 30 minutes at most, light the sky for about a mile. Possibly due to other light shows. But still noteworthy.
