The Solar Cycle [PDF]

open access: yesLiving 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

Solar Cycle Prediction [PDF]

open access: yesLiving Reviews in Solar Physics, 2010
A review of solar cycle prediction methods and their performance is given, including forecasts for cycle 24. The review focuses on those aspects of the solar cycle prediction problem that have a bearing on dynamo theory.

Forecasting the number of sunspots for solar cycle 25 utilizing the facebook prophet model [PDF]

open access: yesScientific Reports
The 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.

Charting the solar cycle

open access: yesFrontiers 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 ...

The Solar Cycle

open access: yesLiving Reviews in Solar Physics, 2010
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. We examine a number of other solar activity indicators including the 10.7 cm radio flux, the total solar ...

A solar energy desalination analysis tool, sedat, with data and models for selecting technologies and regions

open access: yesScientific Data, 2022
There is interest for desalination technologies powered by solar energy as arid areas are typically bestowed with good solar potential. In response to a US DOE call for solar desalination analysis tools, we developed an open-source solar energy ...

A brief review on the presentation of cycle 24, the first integrated solar cycle in the new millennium [PDF]

open access: yesAnnales 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]

open access: yesJournal 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]

open access: yesAnnales 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 ...
