Social media and mainstream news were put on alert as a green fireball struck over Buenos Aires, Argentina on July 30, 2015.
Now, some report another mysterious green light flying over Cordoba, Argentina, the day after and almost at the exact same time! Weird coincidence?

So what was really the green light that lit up the sky on Friday, July 31, 2015. A second fireball? Space junk?
The sky phenomenon lasted for about 15 seconds passed over the north of Cordoba.
In this video, the meteor appears at 2:37, after these guys sing a song on their roof in Cordoba:
I would go for another giant fireball. But our solar system is full of space debris!
