1989年8月5日太阳边缘活动区之上的绿日冕线

THE GREEN CORONAL LINE ABOVE ACTIVE REGION AT SOLAR LIMB ON 5 AUG. OF 1989

我们观测了1989年8月5日博尔德编号5629号黑子群上方的、具有激发连续谱和明亮节点的绿日冕光谱线。根据连续谱强度估算其电子密度为3×10~9—10^(11)cm^(-3)。半宽达1.2A。不考虑湍流速度求得电子的运动温度为4—5×10~6K。沿视线方向辐射较强区域的大小是0.5×10~9cm。

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 1.2A, 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.
