It gets dark early and since it's already dark in the forest, we had a perfect night sky for viewing. Shortly after lift-off, we saw a bright trail of fire moving upward. As the rocket headed off, the trail turned into a fireball as we looked directly into the rocket from behind.I'm not a photographer, but I managed to get a shot without the flash. This does not do it justice.
Apparently, it was a Delta 2 Rocket, carrying an Italian Radar Satellite into space. Details and the launch sequence are available here.
