Hi Denis
Here is my image of C/2019 Y4 taken last night, from South Woodham
Ferrers in Essex, there is a faint  extension of the nucleus in front of
the comet visible in the image, the collimation of the telescope is
slightly out, hope to put that right tonight. The image is 2x2 binned
giving 1.84 arc sec /pixel. I think 1x1 would be better next time giving
0.92 arc sec /pixel
Best regards Jim Vincent

There are no other condensations visible in my image. The material forward of the comet in the sunward direction is still visible and is fairly well defined (not quite spike like). The nuclear magnitude as measured in Astrometrica with a 9 pixel radius is slightly brighter tonight at 14.8.as opposed to 15.1 last night
