Next two tables are showing how many times each Kp-value (maximum and average values) has occurred in each year. As we know, the Kp can have value between 0 and 9 with steps of 0.33. Values in the tables are rounded to nearest integer, which means that for e.g. Kp 2.67, 3 and 3.33 are all counted as 3, and correspondingly 3.67, 4 and 4.33 are counted as 4 and so on.

Interpretation of the tables is quite straightforward. For example from the first table we can see that in year 2015 there were 28 days, when the highest measured official Kp-value has been 1 (and as explained earlier, this includes also values 0.67 and 1.33), and three days, when the highest measured Kp was 8 (7.67-8.33). From the second table we can see that on the same year there were 32 days, when the average Kp-value of the day was 4. In this table the values are rounded slightly differently, because averages are calculated from the average Kp-value of the whole day, and therefore doesn't follow the steps of 0.33. For example average Kp value 4 includes all values from 3.5 to 4.49.

Next diagram contains averages of monthly Ap-values starting from January 2000. Ap-value is calculated by multiplying each of the eight daily Kp-value with specific factor, summing all of the monthly Ap-values and dividing sum with number of days for the same month.
