Abstract

Abstract

The green coronal line above sunspot group of No.5629 of 5 Agu. of 1989 with excited continuum and bright knots is observed. According to the intensities of the continuum, the following parameters are estimated: the electron densities are 3×10⁹-10¹¹/cm, half width is up to 1.2Å, temperature is 4-5×10⁶ K without considering turbulent velocity, and the sizes of strong radiation regions along the direction of line of sight are 0.5×10⁹cm.
