Two nights earlier I have had a chance to observe whats left of the comet from
Weimar, Germany. The comet was at an altitude of only 5.5° above horizon but I
gave it a try with my RASA 11" and ASI6200MC as conditions were exceptionally
good for my location.
The brightness near the head (green color channel) as measured within an
aperture of 3' is
  2025 04 26.84 UT, m=9.8mag
and the tail extent is about 20' at P.A.=333°

I am attaching the stacked image (12 minutes total exposure time) and an
inverted star trail subtracted and stronger smoothed image to highlight the
dust tail.
