Image Details
Caption: Figure 1.
A median-stacked image of all eight 370 s science exposures taken by HST WFC3 of V6 on 2024 December 5. Each exposure has been shifted in x and y to minimize differences between frames and to correct for small differences in the WCS solution. A median stack centered on the JPL-predicted location of V6 is shown on the left, with the cyan box highlighting the expected location and the red box highlighting the area shown in the image on the right. A 4﹩\mathop{.}\limits{^{\prime\prime} }﹩ scale bar, the size of the coma as observed in late 2023, is shown inset in the image on the left for context. In a 5-pixel aperture the signal-to-noise ratio is 17.
