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

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 ...

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.

First Type III Solar Radio Bursts of Solar Cycle 25 [PDF]

open access: yes, 2022
The minimum of the previous solar cycle, Solar Cycle 24, occurred in December 2019, which also marked the start of the new Solar Cycle 25. The first radio bursts of the new solar cycle were observed in the spring season 2020. In this work we will present

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 ...

Solar Cycle Variation in Solar Irradiance [PDF]

open access: yesSpace Science Reviews, 2014
The correlation between solar irradiance and the 11-year solar activity cycle is evident in the body of measurements made from space, which extend over the past four decades. Models relating variation in solar irradiance to photospheric magnetism have made significant progress in explaining most of the apparent trends in these observations.

The solar oscillations spectrum and the solar cycle [PDF]

open access: yesSymposium - International Astronomical Union, 1988
During the summer seasons of the years 1977 to 1985 daily velocity measurements of solar global oscillations have been obtained using a resonant scattering spectrometer. After calculating the power spectra of the daily residuals, the mean for each season is found.
