Dataset of Solar Wind Shocks and GICy-indices for Solar Cycles 23 and 24

Dataset of solar wind shocks and GIC<em>_y</em>-indices for solar cycles 23 and 24 (CFA-SC23 and CFA-SC24) obtained using the Harvard Centre for Astrophysics (CFA) solar wind shock database and geomagnetic field data from the Australian region. Columns 1-5 show the year, month, day, hour (UT), minute, of the solar wind shock; Columns 6-9 show the ground magnetic field change dB (nT) and GIC-index values for the x- and y-components respectively; Columns 10-12 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind IMF B_z (nT); Columns 13-15 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind IMF B_t (nT); Columns 16-18 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind V_x (km/s); Columns 19-21 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind V_t (km/s); Columns 22-24 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for solar wind density (cm^-3); Columns 25-27 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for calculated solar wind dynamic pressure Psw_x (nPa); Columns 28-30 show the pre-shock (minimum values), the post-shock (maximum values), and the calculated step change for calculated solar wind dynamic pressure Psw_t (nPa); Columns 31-36 provide the station abbreviation, geographic latitude and longitude, geomagnetic latitude and longitude, and declination; Columns 37-40 are observing satellite, shock normal angle, shock Mach number, shock type (all events in the table are Fast-Forward shocks); and Column 41 provides the calculated decimal time (hours), ∆t, of the geomagnetic station from local noon for each event.
