NBC News - A suspected meteor flash briefly transforms night to day in Argentina
Cosmic Log reports: "A suspected meteor flash wowed observers in Argentina early Sunday — and sparked memories of February's more serious blast over Russia. The fireball lit up the night in north and central Argentina at about 3:30 a.m. local time, according to accounts from Argentine news outlets. "The sky lit up completely for a couple of seconds and interrupted the calm in this area of Argentina," BarrioOeste.com reported. Witnesses in Catamarca, Tucuman and Santiago del Estero reported sightings."
