Observer
Name Sebastian H
Experience Level 2/5
Remarks The object was visible at least a second before I saw it directly, since I first noticed its shine from behind me. A friend was with me at the moment, she neither saw that the trail was double, nor the two explosions, nor did she hear the faint booms.
