Two peaks high rates of shooting stars were predicted for November 19, 2002. The first one, near 4h UT was seen over Europe and northern Africa, the second one, near 11h UT, was observed from the Americas. The graph shows the activity in terms of a Zenithal Hourly Rate which scales meteor rates to a visual limiting magnitude of +6.5 and zenith position of the Leonid radiant.

The solar longitude denotes the position of Earth on its orbit
