Narrative:

On short final we encountered a drone approximately 1300 feet AGL just to the right of the runway centerline. I was the pilot monitoring and the flight operated normally up to the final approach fix. The captain pilot flying (PF) had just directed gear down; full flaps just prior to the encounter. I saw out of the corner of my eye a dark object just [to] the right of the aircraft; but perceived it to be either a reflection (the sun was to our left and behind a little); or possibly a balloon. I initially dismissed it; until the aircraft in front of us began talking to tower about a drone on short final at approximately 1000 feet. I estimate the drone was 2-3 feet in diameter; dark in color; and roughly 30-50 feet right and slightly above our position on final. We reported our encounter to tower after landing.
