AB: During almost three decades of operation, the IMP-8 satellite collected an extensive amount of both plasma and magnetic field measurements. The entire dataset has been searched for all Earth's bow shock crossings observed by IMP-8 and more then 11,000 crossings were found. Due to the IMP-8's orbital trajectory, most of the bow shock crossings were observed at the magnetospheric flanks where the Xgse position was between 0 and -20 Re while the Zgse positions between -20 and 20 Re. About 5000 individual bow shock crossings were used in this study to investigate the bow shock's cross-section: deviations from the circular profile, IMF orientation and Mach number effects on its shape.
