Observer
NameJon C
Experience Level2/5
Remarkszero tail, perfectly round, extremely large, did not burn up, extremely low, color was slightly changing, zero sound, appeared to be extremely close to my position. lasted extremely long time, like 5 to 10 seconds, it never faded, bright until behind foothills, appeared it was going to hit the foothills but went behind. your arrow of its trajactory appeared to be exactly correct, however closer to my position. it appeared that it must of hit the mountains before the divide, because it was so low, but that was probably an optical illusion and may have hit behind the divide somewhere
