P/2003 T12 is a periodical comet that is observed in the sky every 10–15 years.[1] On January 13, 2012, it was observed by the satellite STEREO-B, and the most documented phase of P/2003 T12 was observed on that date.
January 12, 2012 Event
[edit]During its apparition on January 12, 2012, 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. This has given insight into Henyey-Greenstein (HG) space-dust.[2]
