We present a new long-duration parallax event from the OGLE-II database, sc5 2859, which has the second longest time-scale ever identified (tE = 547.6 +22.6 −7.8 days). We argue that both the lens and source reside in the Galactic disk, making event sc5 2859 one of the first confirmed examples of so-called disk-disk microlensing. We find that the source star is most probably located at a distan...
