J-band composite image of T2. The image was boxcar smoothed in the 3-pixel width and overlapped with contours at 90, 50, 25, and 5% of T2’s peak brightness. The “S” marks a background star. A radial profile is given over the inner coma region (enclosed by a dashed-line square of 20″ × 20″) in the lower right corner. The negative velocity (−v) and solar radius (r_⊙) vectors are given.
