The research about relations between sunspot number and Dst index which is the index of geomagnetic disturbance at low latitude had been studied. This research has purposes to know the relation of sunspot number yearly with geomagnetic storm events varied by (1) -50 ≤ Dst Index ≤ -30 (2) -100 s Dst Index < -50 (3) -200 ≤ Dst Index ≤ -100 (4) Dst Index ≤ -200 nT. Data of sunspot number…
