Hα emission components from the jets over the last 7 nights of observation. The left panel shows the approaching jet components and the right panel shows the receding components (with a reversed wavelength scale so that the Doppler shifts can be easily compared between panels). Each spectrum is placed so that the continuum is aligned with the time of observation and is scaled in intensity so that the continuum strength is equivalent to 0.5 days on the y‐axis. Tick marks indicate the central position of each component as determined by Gaussian fitting.
