Sunspot Number Prediction Using Gated Recurrent Unit (GRU) Algorithm [PDF]

IJCCS (Indonesian Journal of Computing and Cybernetics Systems), 2021
Sunspot is an area on photosphere layer which is dark-colored. Sunspot is very important to be researched because sunspot is affected by sunspot numbers, which present the level of solar activity. This research was conducted to make prediction on sunspot

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

Scientific 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.

Sunspot numbers: Implications on Eastern African rainfall [PDF]

South African Journal of Science, 2014
Following NASA’s prediction of sunspot numbers for the current sunspot cycle, Cycle 24, we now include sunspot numbers as an explanatory variable in a statistical model. This model is based on fitting monthly rainfall values with factors and covariates
