Figure 5: ((a)—D). The intense center (~1°) of the jet begins to produce light as it penetrates into the polar ejecta, producing the jump in luminosity at day 9.8. ((b)—E) Particles in the jet continue to impact the polar ejecta (mostly hidden), extending the ramp in luminosity visible in Figure 3 near day 20 (left dashed line to the top scale). Right dashed line: light from the filtered UV flash scatters in clumpy polar ejecta near its outer boundary. ((c)—F) The fastest jet particles have cleared the end of the polar ejecta.
