Estimates for the remaining lifetime, τ, of the three switchbacks discussed in this paper, and the convection distance, D, travelled by the switchbacks before they fully erode away.
| Event | Λ (km) | Bl, SB (nT) | Bn, out (nT) | vl, out (km s−1) | |⟨vp⟩| (km s−1) | τ (min) | D (au) |
|---|---|---|---|---|---|---|---|
| Event 1 | 3570 | −4.8 | −1.0 | −7.2 | 322 | 40 | 0.005 |
| Event 2 | 10100 | −9.7 | 0.5 | −28.3 | 439 | 126 | 0.02 |
| Event 3 | 31700 | −7.5 | −0.1 | 15.4 | 443 | 2005 | 0.4 |
Notes. Λ: switchback width, BSB: magnetic field strength in the switchback, Bout: magnetic field strength in the outflow region, vout: exhaust outflow bulk speed, ⟨vSW⟩: average solar wind speed.
