ABSTRACT

It is known that sunspot cycle as solar that is about 11 years change from the sun’s activity. Also the period of solar cycle, the number and size of sunspot and coronal loops all exhibits a synchronized fluctuation. The flip occurred if the solar cycle is near its maximum due to the magnetic field from the sun. There are regions of reduced surface temperature due to the concentration of magnetic flux that inhibit convection. Also the group of sunspot would last from a few days to a few months. The goal of this work is obtain to the correlation of geomagnetic Ap-index CRz-Ap and CRz-Dst. The method used is the Zurich number for the sunspot. The Sunspot Area (SSA), International Sunspot Number (ISSN), Solar X-ray peak flux, Maximum Coronal Mass Ejection Speed index (MCMESI), geomagnetic Ap and Dst index were used. The result obtained is the Sunspot Potential. Geomagnetic Ap and Dst index were Observed. The Geomagnetic CRz-Ap and CRz-Dst index are achieved.
