Leonid ZHR between 7h and 13h UT (Nov 18, 2001)
Analysis of observations from Mt. Lemmon, AZ, show a ZHR of 400±100 around 7:30 UT rising to storm level of 1000 around 09:35±5min. A first distinct peak appears at 10:42±5min with ZHR 3800±100. A second peak appears around 11:02±5min with ZHR 4000±100. ZHR then drops to ~700±100 at the end of observations, between 12:30 and 12:55 UT.
Remark: ZHR values were calculated with r=2.0 and gamma=1.0. ZHR values might differ from those calculate by IMO due to a smaller observation sample and individual observer perception coefficients. Observations were made from Mt. Lemmon Observing Facility (2871m).
