Narrative:

On initiation of takeoff power 'aft entry' door light illuminated. Rejected takeoff, airspeed was at 20 KIAS. With minimal braking, exited at taxiway M (next taxiway). After brief discussion with flight attendants, we determined that right rear door handle was up at 1-2 inches (from full down position, door was closed and secure). Handle was put in full down detent, light out, taxied back for uneventful takeoff.
