This is a town that happened to have its biggest celebration of the year last night. It's called Festas do Senhor de Matosinhos.
The meteor made an appearance 15 minutes before midnight. The big fireworks were to go off at midnight. We all thought it was the weirdest firework we'd ever seen and only later realized it was a meteor.
It was truly huge. And lit the ground blue.
The really interesting part of this is that the festival is to celebrate a miracle in the town wherein a vision of Jesus appeared a long time ago.
I am not religious. But wow. Quite a coincidence.

Maybe this sounds unbelievable but here is the program of the festival where you can see that the fireworks happen:
