Narrative:

I was jumpseating in the cockpit. [At] 700 AGL; 2100 ft from the runway; I noticed what I first thought was a balloon; stationary or moving from our 10:30 or 11 o'clock toward our left wing 9 o'clock. I did not see the threat as significant enough to distract the pilots. As we continued; at about 700 AGL the object; which was now in our 9:30 position; at our altitude; was clearly a small white uav. I asked the pilots if they saw the drone off to the left and they replied that they did not. The drone was reported to the tower who requested that we call the approach control facility. I reported the event to ATC; [the local law enforcement] office; and eventually to the FAA.
