This report has been linked to the following event: Event 4310-2017
Observer
NameJohn A
Experience Level1/5
RemarksThe first awareness of the fireball was directly overhead as it lit the night sky for about 2 seconds. The light was as intense as a lightening strike, but was steady and lit up the entire forest in the immediate area in which we were camped. It quickly arc'd and the light was extinguished as the fireball disappeared over the horizon. Two explosions followed about 30 seconds later. I am keenly interested in knowing if there was a meteor event, or if this description has a common explanation. This was not at all like a shooting star or like a comet. First impressions were that a helicopter was hovering overhead with extremely bright lights, however, no sounds accompanied the light or the arcing glowing fireball.
