I caught it on my phone camera. It took just over a minute from when I could see the flames burning brightly to disappearing into the distance. The 7-8 fireballs seemed to keep a constant altitude and speed they also had varying sizes. Its the coolest thing I have ever seen in the sky :) I never heard of fireballs before. :)
