Time profiles of key geomagnetic parameters (Ap and Dst indices) are shown together with key parameters of the solar wind (velocity V, density n and temperature T) and IMF (B, Bx, By, Bz in GSM coordinate system). This data representation permits to identify the interplanetary agent (CME, CIR, Erupted Filament etc.) triggering the magnetospheric disturbance. There are two kinds of plots: 3 day duration (for searching fast processes) and 7 day duration for analysis of global (previous and following) heliospheric and geomagnetic situation (especially in the case of complicated events). The middle day of the pictures is a day from the List of selected geomagnetic disturbed days .

Geomagnetic activity dynamics is presented on two upper panels as time profiles of Ap and Dst indices. Geomagnetic data is obtained from WDC-C2 KYOTO Geomagnetic Data Service. Vertical dashed line corresponds to the time of maximal Ap-index observed during geomagnetic disturbed day.
The parameters of solar wind plasma (velocity V, density n and temperature T) are presented on the next three panels. Hourly averaged data from OMNIWeb are indicated by symbols: circles (V) and triangles (n and T). High time resolution data on the solar wind plasma is obtained from Wind experiment in 1997 and ACE experiment in 1998-2002 using ISTP data base. On the bottom two panels IMF B, Bz (dotted and solid lines respectively) and Bx, By (solid and dotted lines respectively) are presented in GSM coordinate system. The IMF data is obtained also from ISTP data base using Wind experiment in 1997 and ACE experiment in 1998-2002.
Using the maximal velocity measured within 12 hours before the maximal Ap-index detection, the possible time of the solar wind start from the Sun was calculated. This starting moment is used for selection of most probable solar events presented on 1d Map of Solar Events
