Living Reviews in Solar Physics, 2015 The solar cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise and fall in the numbers and surface area of sunspots. A number of other solar activity indicators also vary in association with the sunspots including; the 10.7

Forecasting the number of sunspots for solar cycle 25 utilizing the facebook prophet model [PDF]
Scientific ReportsThe solar cycle, also referred to as the solar magnetic activity cycle, represents a nearly periodic change in solar activity occurring approximately every 11 years, as evidenced by the observation of sunspot numbers.

A brief review on the presentation of cycle 24, the first integrated solar cycle in the new millennium [PDF]
Annales Geophysicae, 2011 The status of the extended solar activity minimum, since the second half of 2007, has been briefly instructed to the solar-terrestrial community. Cycle 24 has the most spotless days since cycle 16, and probably even since the modern cycles, latitudes ...

Frequency of Solar Spotless Days and Flare Index as Indices of Solar Cycle Activity [PDF]
Journal of Astronomy and Space Sciences, 2014 There was a research on the prolongation of solar cycle 23 by the solar cyclic variation of solar, interplanetary geomagnetic parameters by Oh & Kim (2013).

Prediction of solar activity on the basis of spectral characteristics of sunspot number [PDF]
Annales Geophysicae, 2004 Prediction of solar activity strength for solar cycles 23 and 24 is performed on the basis of extrapolation of sunspot number spectral components. Sunspot number data during 1933-1996 periods (solar cycles 17-22) are searched for periodicities by ...

Frontiers in Astronomy and Space Sciences, 2023 Sunspot records reveal that whilst the Sun has an approximately 11 year cycle of activity, no two cycles are of the same duration. Since this activity is a direct driver of space weather at Earth, this presents an operational challenge to quantifying ...

Solar cycle-related variation in solar differential rotation and meridional flow in solar cycle 24
Earth, Planets and Space, 2020 We studied temporal variation of the differential rotation and poleward meridional circulation during solar cycle 24 using the magnetic element feature tracking technique.

Predicting solar cycle 24 with a solar dynamo model [PDF]
, 2007 Whether the upcoming cycle 24 of solar activity will be strong or not is being hotly debated. The solar cycle is produced by a complex dynamo mechanism. We model the last few solar cycles by `feeding' observational data of the Sun's polar magnetic field ...

International Journal of Geophysics, 2012 We analyse the variability of foF2 at two West Africa equatorial ionization anomaly stations (Ouagadougou and Dakar) during three solar cycles (from cycle 20 to cycle 22), that is, from 1966 to 1998 for Ouagadougou and from 1971 to 1997 for Dakar.
