Zenithal Hourly Rate
In
astronomy
, the
Zenithal Hourly Rate
(ZHR) of a
meteor shower
is the number of meteors an observer would see in one hour under a clear, dark sky (limiting
apparent magnitude
of 6.5) and if the
radiant
of the shower were in the
zenith
. The rate which can effectively been seen is always lower and decreases as the radiant is closer to the
horizon
. See also
