Power law relating 10 . 7 cm flux to sunspot number
Robert W. Johnson Alphawave Research, Atlanta, GA 30238, USA (Dated: December 26, 2009) Abstract To investigate the relation between observations of the 10.7 cm flux and the international sunspot number so that a physical unit may be ascribed to historical records, both polynomial and power law models are developed giving the sunspot number as a function of flux and vice versa. Maximum likeliho...
متن کاملDecreasing Sunspot Magnetic Fields Explain Unique 10.7 cm Radio Flux
Infrared spectral observations of sunspots from 1998-2011 have shown that on average sunspots changed; the magnetic fields weakened and the temperatures rose. The data also show that sunspots or dark pores can only form at the solar surface only if the magnetic field strength exceeds about 1500 Gauss. Sunspots appear at the solar surface with a variety of field strengths, and during the period ...
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 کاملLinearized pipe flow to Reynolds number 107
A Fourier–Chebyshev Petrov–Galerkin spectral method is described for high-accuracy computation of linearized dynamics for flow in an infinite circular pipe. Our code is unusual in being based on solenoidal velocity variables and in being written in MATLAB. Systematic studies are presented of the dependence of eigenvalues, transient growth factors, and other quantities on the axial and azimuthal...
متن کاملAnalysis of Sunspot Number Fluctuations
Monthly averages of the sunspot number visible on the sun, observed from 1749, Zurich Observatory, and from 1848 other observatories, have been analyzed. This time signal presents a frequency power spectra with a clear 1/f behavior with α ≃ 0.8±0.2. The well known cycle of approximately 11 years, clearly present in the spectrum, does not produce a sensible distortion of that behavior. The event...
