Abstract:
We present the coronal index of solar activity (CI) for 1996. To compute CI,
we used only the intensities of the green corona from Lomnicky Stit and
Sacramento Peak coronal stations. Values of CI were low with an increase
toward the end of 1996. It appears that the minimum of solar activity in the
green corona occurred in March 1996. The rotational rate of CI, as measured
during the last half of 1996, is 26 days. The results are compared to the Wolf
number and 2800 MHz flux over the entire cycle 22 (1986-1996).
