A sequence of 117 temporal maps, with fine-scale difference enhancement, C/2011 L4's clumpy tail region. The tail is shown from 2013 March 13 00:00 UT until March 16 12:00 UT. Dust is displayed in the region of 4 < βr < 20 with ejection times from 2013 March 11 00:00 UT through to March 14 00:00 UT.
The upwards motion of the feature released after midday on the 12th is common for the features seen in this part of the tail when temporally mapped. Such anomalous motion would appear to rule out Finson-Probstein type physics for this part of the tail.
