The web site of WDC for Geomagnetism at Kyoto U., url given below, offers plots and numeric downloads for 1-hour Dst and related indices. The data are currently (as of 12/07/2011) "final" from January, 1957, through December, 2008, and are "real time" thereafter, through the current day. Alternative sources of many of the WDC/Kyoto-generated Dst and related indices include the hourly OMNI data set at NASA/GSFC/SPDF.
