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.

Magnetic Helicity as a Predictor of the Solar Cycle. [PDF]
Sol Phys, 2018 It is well known that the polar magnetic field is at its maximum during solar minima, and that the behaviour during this time acts as a strong predictor of the strength of the following solar cycle.

SOLAR CYCLE 25: ANOTHER MODERATE CYCLE? [PDF]
The Astrophysical Journal Letters, 2016 Surface flux transport simulations for the descending phase of Cycle 24 using random sources (emerging bipolar magnetic regions) with empirically determined scatter of their properties provide a prediction of the axial dipole moment during the upcoming ...

Understanding Solar Cycle Variability [PDF]
The Astrophysical Journal, 2017 The level of solar magnetic activity, as exemplified by the number of sunspots and by energetic events in the corona, varies on a wide range of timescales.

Living 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 ...

Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum [PDF]
Space Science Reviews, 2023 Launched on 12 Aug. 2018, NASA’s Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission’s primary science goal is to determine the structure and dynamics of the Sun’s coronal magnetic field, understand how

Physical Models for Solar Cycle Predictions [PDF]
Space Science Reviews, 2023 The dynamic activity of stars such as the Sun influences (exo)planetary space environments through modulation of stellar radiation, plasma wind, particle and magnetic fluxes. Energetic solar-stellar phenomena such as flares and coronal mass ejections act

Progress in Solar Cycle Predictions: Sunspot Cycles 24–25 in Perspective [PDF]
Solar Physics, 2020 The dynamic activity of the Sun—sustained by a magnetohydrodynamic dynamo mechanism working in its interior—modulates the electromagnetic, particulate, and radiative environment in space.

Extreme Space-Weather Events and the Solar Cycle
Solar Physics, 2021 Space weather has long been known to approximately follow the solar cycle, with geomagnetic storms occurring more frequently at solar maximum than solar minimum.

Nonlinear Mechanisms that Regulate the Solar Cycle Amplitude [PDF]
Astrophysical Journal, 2020 The solar magnetic activity cycle has an amplitude that varies within a wide but limited range of values. This implies that there are nonlinear mechanisms that prevent runaway solutions.
