Clearly show breakup of the nucleus - or at least several condensations, to be interpreted somehow!</div>

Image 6.2' wide - ive upsampled it 2x to make it clearer. Original resolution 0.72"/pixel, so ~1.44"/pix here.</div>

<div class="PlainText">As of this evening (April 6) my astrometry now shows a residual of 6
<br>
arcsec in RA (approx in the direction of the tail). I've plotted the <br>
brightness profile of the comet in a slice through the nucleus and <br>
parallel to the tail for three dates, 2020 March 31, April 5 and April <br>
6. The peak brightness is falling and the inner coma is broader in the <br>
tailward direction. All of this implies this comet may not last much <br>
longer. I hope I'm wrong but observe it while you can!<br>
