Upstream solar wind observations. a Magnetosheath magnetic field at THB in GSM components (x, y, z as blue, green, red) and magnitude (black). Observations within the magnetosphere have been removed for clarity. The times of the magnetosheath jet are shown by vertical black dotted lines. b–j Lagged Wind observations of the pristine solar wind b magnetic field GSM components (x, y, z as blue, green, red) and magnitude (black), c cone angle, g density, and i speed. The significance of their respective wavelet spectra are also shown d–f, h, j, where the power has been divided by an autoregressive noise model. Dotted horizontal lines depict frequencies of 1.7–1.8 and 3.3 mHz
