The median-combined images of 289P (center) in Visit B (MJD 58860: UT 2020 January 11–12, outbound). Both frames have a size of 200″ × 200″ with an integration time of 15.4 s. The left panel shows the W1-band image with FWHM θF = 6﹩\mathop{.}\limits^{{\rm{^{\prime} }}{\rm{^{\prime} }}}﹩6, while the right panel shows the W2-band image with θF = 6﹩\mathop{.}\limits^{{\rm{^{\prime} }}{\rm{^{\prime} }}}﹩ 9. A 40″ scale bar is included. Rh = 1.01 au, Δ = 0.09 au, and α = ﹩70\mathop{.}\limits^{\circ }2﹩. North and east exhibit the cardinal directions. −V shows the direction of the negative heliocentric velocity vector and −⊙ shows the antisolar direction.
