Single- and double-station video observations of the 1999 Leonid shower made from Israel are presented. A total of 232 double-station Leonids had trajectories computed. Additionally, some 2500 single-station Leonids were used to measure the Leonid storm flux and mass distribution in the interval from 0.5-3UT 18 November 1999. The height distribution for storm Leonids of average mass ~10-6-10-7kg indicates that the ablation zone is approximately Gaussian-shaped with best-fit mean begin, maximum brightness and end heights of 123.3+/-0.7,107.3+/-0.42 and 95.0+/-0.56km respectively. The peak flux at the time of the storm was found to be 0.81+/-0.06meteoroidskm-2hr-1Mv<+6.5. using 15min binning and 0.99+/-0.11meteoroidskm-2hr-1Mv<+6.5 for 3min intervals. The smaller temporal resolution reveals a broad plateau in flux lasting from approximately λ0=235.276-/235.285° (J2000.0). At least one significant feature in the rate curve is apparent near /235.272°, which we suggest is associated with material released in 1932. The video mass distribution index over the course of the Leonid storm was found to be constant near /s=1.75. The peak time of the storm estimated from 15min sampling of the flux profile is near /235.283+/-0.005° (/1h58m+/-7m) while 3min resolution data place the maximum at /235.281+/-0.003° (/1h55m+/-4m). The mean radiant position at the time of the storm was found to be /α=153.1+/-0.1° and /δ=21.5+/-0.2° (J2000), with some hint of a more compact radiant grouping within the range /α=153-/154° and /δ=21-/22°. We do not find evidence for any significant high altitude Leonid population at video masses despite biasing one camera pair to an intersection altitude of 160km.
