Özet:

 

In this study, we modified the previously introduced   X-ray flare production potential (FPP) of each modified Zurich sunspot group   based on its X-ray flare peak flux. Then, using these FPPs, the daily total   sunspot number (Zurich number) calculation equation was modified; thus, new   sunspot number data (CRz) were produced. We also compared ISSN and CRz with   some geomagnetic indices (Dst, the maximum CME speed, and Ap indices). We   found that the CRz data describe the geomagnetic indices quite well compared   to ISSN. By using the regression equation between CRz and the sunspot area,   the CRz dataset was recalculated back to 1874. Those reconstructed datasets   were compared to observational data, and it was found that reconstructed and   observed monthly datasets show very good agreement. The only small   differences exist in maxima and minima of cycles.
