Dst versus Bz relation for geomagnetic storms in the 23rd solar cycle

In the study, the statistical analysis of the peak values of geomagnetic index Dst for 1497 disturbances revealed from 1997 to 2006 was performed. The cases of DstDstDst vs Bz relation. The Dst in respect of Bz delay time is usually from 3 to 6 hours.
