Macholz...what's up with the ion tail?

Here is my first image of Comet Macholz acquired last night- the first clear night without a significant moon of the year.

After seeing Stefan Seips's gorgeous image I had anticipated more ion tail detail but it appears things have changed as even the luminance frame only faintly shows the tail structure. Anybody have any recent images since the dislocation?
