(meteorobs) Nov 17/18 magnitude distributions



Here is my data for Leonid magnitudes during the peak night, as seen 
from southern Spain. Data is again broken down into shorter 1 minute 
periods during high activity. Between 2:02 and 2:22, Leonids were too 
numerous to assign magnitudes, so there is no data for that period.
