My daughter and I witnessed four deep orange fireballs above the eastern side of the Wasatch front mountain range, just east of Salt Lake City. The event lasted about 10 minutes. We spotted them from our balcony, and they seemed to resemble aircraft flairs because they appeared at a height that is typical to aircraft and drifted downwards.
After observing them drift downwards for a few minuted, two then faded out of sight. The other two began to float upwards and hovered for about two minutes, then down again behind the mountains.
Within about one minute, one drifted up from behing the mountains, then hovered, and faded out of sight.
