This looked like it entered Earth's atmosphere. It did not look like a far off shooting star or meteor. It was amazing!

Remarks
The green fireball looked very close and much larger than shooting star. I expected to hear about it in news next day. Glowing train, larger closer to fireball, tapered toward back.
