Extended Data Fig. 1: Overview of the second PSP encounter with the Sun.
From: Alfvénic velocity spikes and rotational flows in the near-Sun solar wind
The figure is in the same format as Fig. 1. Spikes in the velocity are again seen to be coincident with the magnetic-field reversals, but the jump in the speed is smaller, probably because the Alfvén speed was lower in E2 than E1. The density at perihelion is substantially lower.
