| Abstract: | By analyzing the relationship between the disturbance amplitude of a single geomagnetic station＇s data and the geomagnetic planet indices of Ap and Kp for a long time, a fast and simple method for the Ap estimation on fitting the daily average of one hour disturbance amplitude of magnetic is presented. Based on the logarithmic fitting of the Kp and the average of r, in three hours, we can get the estimating method of Kp index. According to the above mentioned methods, using the geomagnetic minutes data of H component from 2003--2008 of Zhaoqing station to estimate the planetary indices of Ap and Kp, and comparing with the Ap and Kp indices from the Word Data Center. Results show that, in accordance with the above method using the Zhaoqing geomagnetic data to estimate Ap and Kp indices is feasible in a certain error range. |
