A study on Ca II 854.2 nm emission in a sunspot umbra using a thin cloud model
In the present work, we introduce and explain a method of solution of the radiative transfer equation based on a thin cloud model. The efficiency of this method to retrieve dynamical chromospheric parameters from Stokes I profiles of Ca II 854.2 nm line showing spectral emission is investigated. The analyzed data were recorded with the Crisp Imaging Spectro-Polarimeter (CRISP) at Swedish 1-m So...
متن کاملAbsence of Correlation between the Solar Neutrino Flux and the Sunspot Number
There exists a considerable amount of research claiming a puzzling anti-correlation between the neutrino detection rate at the Homestake experiment and indicators of solar activity such as the sunspot number, giving rise to explanations involving the hypothesis of a neutrino magnetic moment. It is argued here that the claimed significant anti-correlation is due to a statistical fallacy. A prope...
متن کاملThe Differences in the Relationship between Ionospheric Critical Frequencies and Sunspot Number for Different Sunspot Cycles
Analysis of data for Washington and Watheroo indicates differences in the relationship between føF2 and sunspot number for the current and preceding sunspot cycles. The sunspot number is therefore not entirely satisfactory as an index for ionospheric variations. Consequently, ionospheric data for the current cycle only should be used in preparing ionospheric radio propagation predictions whenev...
متن کاملSunspot Number Corrections
Let me try to say things a bit more clearly. Reconstruction of the EUV flux is on solid ground based on the range of the diurnal variation, rY, of the Geomagnetic East Component: The process is described
متن کاملOn the correlation between Ca and Hα solar emission and consequences for stellar activity observations
Context. The correlation between Ca and Hα chromospheric emission, known to be positive in the solar case, has been found to vary between -1 and 1 for other stars. Aims. Our objective is to understand the factors influencing this correlation in the solar case, and then to extrapolate our interpretation to other stars. Methods. We characterize the correlation between both types of emission in th...
