Abstract: In the present examination we investigate the relationship of geomagnetic storms with the CRI, and Ap index during ascending and descending phase. Our analysis comprises the study of solar cycle 22 and 24. In order to set up the relationship between these parameters we have used the superposed epoch method. During the analysis of both solar cycles we have found a very interesting outcome that the intense value of Dst leads to the intense value of CRI for both phases. We have likewise compared the patterns of Ap index with Dst and CRI and found that the minimum peak of Dst and CRI coincides with the maximum peak of Ap index.

Keywords: Geomagnetic storms, Cosmic ray intensity, Ap index, Dst.
