Geminids in Columbia by Leonardo Ariza

Saludos Amigos,The best meteor shower I've seen so far, the Geminds are a sublime spectacle; fascinating! I was in a remote place of this beautiful Colombian geography, with a sky compeltely clear, so we could get these photos. Here I am writing in the middle of nowhere, with a very slow internet connection, but I could not withstand the urge to share this experience with everyone. Separated by space, I experiences this event simultaneously with my father, who was in Bogota and saw a large bolide amid a cloud, but as he tells me, it is also clear skies.
 
The Geminids are distinguished by their origin, while the other showers are associated with comets, the Geminids appear to have their origin in an object called 3200 Phaethon, an asteroid or perhaps cometary nucleus old and worn out, therefore, the Geminids are several times more dense than the comet dust generated from the other meteor showers. Also they have a low speed of 35 km per second, the essential ingredients for bolides that are the most brilliant and longest lasting.  These photos were made with 24 and 50mm obeť for Bogotana, f / 1.4 and 1.7 Expo 1min and 2min 1000iso.
