This image of C/2019 Y4 (ATLAS) was taken on my fifth consecutive clear night and the forecast is good for the next few nights too. I would be really interested in getting astrometry of the condensation to the NW of the main elongated coma. It is hard to do due to the proximity of the bright coma (in Astrometrica you need to manually set the centroid) but it would seem to be near the position where we would expect the nucleus to be. Please send me any astrometry you get to the Comet Section.
