Description
Lists of bow shock crossings observed by the IMP 8,
Geotail, Magion-4 and Cluster/Rumba spacecraft. For each crossing, time
and spacecraft location are given, plus GSE and GSM components of upstream
magnetic field and solar wind velocity, upstream solar wind ion density
and temperature, and multiple upstream derived parameters (sonic,
Alfvenic and magnetosonic speeds and Mach numbers, plasma beta and flow
pressure, IMF clock and cone angles). In addition, for IMP 8 only,
several additional parameters are given, including downstream density,
shock strength, and various flags related to data quality, etc.).
Time coverage for the various spacecraft is non-uniform; IMP 8
coverage is complete from 1973 launch until the June 10, 2000, failure
of the magnetometer. Annual, spacecraft-specific files of crossings
are ftp accessible as indicated below. Further, the data are accessible
via a value-added interface with the ability to subset by parameter, to
filter by numeric ranges of any of the parameters, and to generate
scatter plots of any one parameter against any other parameter. The
data are extensively documented at the value-added interface and
references therein.
