A turbulent solar wind interval with a clear magnetic hole observed by Solar Orbiter on 2020 June 29. (a) B. (b) n_e, SC. The red crosses are n_e, pk estimated from Langmuir waves. (c) PVI values for τ = 1 s (blue), 10 s (red), and 60 s (gold). (d) and (e) J in SRF and field-aligned coordinates, respectively. The blue-shaded and red-shaded regions indicate times when ion-acoustic and Langmuir wave snapshots are observed by TDS, respectively.
