Comet P/2003 T12 = 2012 A3 (SOHO) was observed by the satellite STEREO-B during the period 2012 January 13–27. During its apparition, it ventured into the highest phase angle ever observed for a comet, and the forward-scattering enhancement in brightness was marked, as large as ∼8.5 mag. Therefore, it provided a precious opportunity to examine the compound Henyey–Greenstein (HG) comet–dust light-s...
