摘要

The newly revised sunspot-number series allows for placing historical geoeffective storms in the context of several hundred years of solar activity. Using statistical analyses of the Geostationary Operational Environmental Satellites (GOES) X-ray observations from the past approximate to 30 years and the Solar and Heliospheric Observatory (SOHO) Large Angle and Spectrometric Coronagraph (LASCO) Coronal Mass Ejection (CME) catalog (1996 - present), we present sunspot-number-dependent flare and CME rates. In particular, we present X-ray flare rates as a function of sunspot number for the past three cycles. We also show that the 1 - 8 angstrom X-ray background flux is strongly correlated with sunspot number across solar cycles. Similarly, we show that the CME properties (e.g. proxies related to the CME linear speed and width) are also correlated with sunspot number for Solar Cycles 23 and 24. These updated rates will enable future predictions for geoeffective events and place historical storms in the context of present solar activity.
