(meteorobs) Leonid Observations From Spain
I had the pleasure to join the IMO expedition to the south coast of
Spain to view the Leonids under near perfect skies. We observed in the
mountain region north of Malaga where the temperature were just above
freezing with a strong wind out of the east. During 5.38 hours of
observing time I counted 1562 meteors, 1519 which were members of the
Leonid shower. The preliminary data will be presented here. A more
detailed report will be forthcoming.

Please note that the rates for the Leonids per minute and per hour was
the OBSERVED RATE and not the Zenith Hourly Rate. The ZHR would be a
factor several times higher.
I was facing east at an elevation of 70 degrees. AMO = Alpha
Monocerotids, LEO = Leonids, NTA = North Taurids, STA = South Taurids,
and SPO = Sporadic (Random Activity).
Several breaks were taken to attend to photographic and recording
equipment.
