State variables for solar active regions
Astronomical & Astrophysical Transactions, 2003In this paper, several integral parameters of solar active regions are defined. The values of these parameters can be calculated from observational data.

Solar active regions at millimeter wavelengths
Solar Physics, 1970Some properties of solar active regions at 9, 3.5 and 1.2 mm wavelengths are discussed. The regions have excess brightness temperatures of up to 1000, 700 and 150 K at 9, 3.5 and 1.2 mm wavelengths. The background radiation at 3.5 mm is often seen to be ‘absorbed’ in regions closely coincident with Hα dark filaments on the disk. Interpretation of this ‘
