A sequence of 211 temporal maps, with fine-scale difference enhancement, showing C/2011 L4's short straight tail. The tail is shown from 2013 March 10 04:50 UT until March 16 12:00 UT. Dust is displayed in the region of of 10 < βr < 300.

The short extent of this tail means that displaying dust on an axis with fixed ejection time and date proves unsuitable. Dust is therefore shown over a fixed range of ages for each image, i.e. when dust was between 0.1 and 2 days old. As such, the dates and times on the axis are not constant, and fixed points with a specific βr and te move along the axis at the same rate as the cadence of images.
