List of meteor streams
This list contains meteor streams that recur every year . The observed fall rate of falling stars is usually highest just before dawn , when the observer is on the front of the earth's movement around the sun. The highest possible fall rate is called the Zenithal Hourly Rate (ZHR) and refers to optimal conditions ( radians close to the zenith , very dark sky with a visual limit of stars up to 6.5 mag ).
Outside of the maximum there are usually only a few meteors per hour. The ZHR of some meteor streams is highly variable, which is related to the current position of the generating comet relative to the earth's orbit, or to the variable density of its dust particles.
