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).
