Fine Scale Structure in Cometary Dust Tails - Figure 5.14 - Stria breaking up seen by STEREO-B at dust point P

A sequence of images extracted from the STEREO-B HI-1 view of C/2011 L4, using coarse scale difference images. The breakup of a stria early on the 14th march is shown, centred on the purple point P which represents a dust particle with β_r = 1.7 and t_e = 2013-03-08 at 04:50 UT.
