I managed this image of C/2019 Y4 (ATLAS) last night after the clouds parted in Chelmsford. I get a total magnitude of 9.0 now using the green channel of this image and a coma diameter in excess of 10 arcmin. Various people report seeing it visually last night. The comet is brightening extremely rapidly as it approaches the Sun. It will be very interesting to see how it develops over the next month.
