Zenithal hourly rate
text:
In astronomy, the zenithal hourly rate (ZHR) of a meteor shower is the number of meteors a single observer would see in an hour of peak activity if the radiant was at the zenith, assuming the seeing conditions are perfect. The rate that can effectively be seen is nearly always lower and decreases the closer the radiant is to the horizon.
