Orange fireball seen slowly rising up in the sky, moving away, then disappearing behind a cloud. Object seen by 4 individuals.While at soccer practice in Riva, MD, approx. 630pm, my son and three of his friends saw 1 Orange light rise up in the sky, fairly slowly. He mentioned whitish sparks coming from the back of it and a smaller Orange ball coming from the larger first ball. I did not see the object, although more than 3 individuals described it exactly as my son did, corroborating his sighting. The Orange ball rose than moved behind a cloud and was not seen after that. My son also mentioned a horn being tripped as the object disappeared.
