Narrative:

Captain was flying and I was on radios. We were cleared to 7000 ft MSL by arrival controller. 7000 ft was set in altitude warning window. (At this point on the arrival we would normally have been cleared down to 6000 ft or less). Captain started descent and I called out the 8000 ft for 7000 ft call. The captain was maneuvering from one radial to another, in a left turn, at about this time. The next thing I knew, all 3 of us simultaneously noticed we were at 6500 ft MSL. The captain added power and smoothly climbed to 7000 ft. Shortly thereafter the controller cleared us down to 6000 ft MSL. No mention of our deviation was made by the controller. Supplemental information from acn 442830: I was getting our gate assignment with the captain descending to 7000 ft at 500 FPM.
