A quick look at the spectrum from this morning suggests the sodium emission is much weaker now.  Colour images of the dust tail certainly look less ‘orange’ which maybe why the ion tail looks much more prominent(?).  I initially put all this down to the poor seeing this morning but I think it’s real.

Will post images/spectra on my members site when I’ve had a closer look.  Was also imaging Gyulbudaghian’s and Borisov’s VNe last night so a lot of images to plough through!!!
