摘要

Sunspots are the most obvious feature on the disturbedsurface of the photosphere above the solar atmosphereand appear to play a key role in major solarand terrestrial disturbances. The solar source activityvaries with a 11-year sunspot cycle. During solaractivity maximum years, maximum transient solaractivity (i.e. solar flares, solar proton events and coronalmass ejections) is released from the Sun andenters the earth’s magnetosphere which is found to beresponsible for producing large geomagnetic storms.In solar activity minimum years, a few geomagneticstorms are observed due to the presence of coronalinteraction regions. We have studied the general characteristicsof past solar cycles 1–23 and predictedabout the present sunspot cycle 24. We conclude thatsunspot cycle 24 is similar to sunspot cycle 22, peakingbetween September 2012 and February 2013. Solarmaximum of sunspot cycle 24 may pose a great risk tosatellite communication, space weather and result ingeomagnetic hazards.
