Observer
Name Johan V
Experience Level 4/5
Remarks difficult to make a report afterwards, was driving when I saw it and I kept driving. My father, 85 years old, besides me saw it too, aothough does not see anymore very well. He confimed the green tennisball and the yellow-orange trail. Like green artificial fireworks, but in a straight trail above the horizon, but same colors. We did not hear anything as we were driving in the car and kept on driving.
