Abstract: This research shows that the moon circulation and motion affects air ionization , where the number of negative ions decreases as the ionization potential decrease as the moon day increases when the sun shine from 3 ok to 5 ok . But at the time interval from 6 ok up to 9 ok the number at negative ions increases gradually from the 5th moon day where it attains its maximum value at the 8th moon day , then it decreases gradually up the 14th moon day. The sun motion also affects the number of negative ions , where it becomes large at 3 ok then decreases gradually up to 6 ok as far as it becomes constant after that up to 9 ok . this confirms the role of sun radiation in increasing the number of ions since degree of ionization decreases as the radiation intensity decreases , then it becomes constant at night when no radiation exists. It was also observed that the number of negative ions increases near plants compared to regions far from the plants.
