Panel a: magnetic field magnitude, panel b: magnetic field vector in VSO coordinates, panel c: STEP Magnet channel ion flux spectrogram, panel d: HET C detector high-gain channel GCR count rate, and panel e: percent of sky blocked by Venus (solid blue), percent decrease of GCR rate (black), and 10-min smoothed percent decrease of the GCR rate (red). The vertical solid red and dotted orange lines indicate the times of the bow shock crossing and Solar Orbiter closest approach (CA), respectively.
