Comet C 2019 Y4 was discovered on December 28th 2019 by Asteroid Terrestrial-Impact Last Alert System (ATLAS) search program. At the time of discovery the comet was from 19.6 mag. This image shows the comet on April 10th 2020. It is obtained by combining the RGB data from IRIDA-North 12" Astrograph and luminance data from 2m RCC telescope of Bulgarian Institute of science and NAO Rozhen. Luminance data are courtesy of Milen Minev (Bulgarian Institute of Astronomy and NAO Rozhen), who photographed the comet on April 10th 2020 at 1:00 UT with Andor iKon-L CCD camera . A composition of 15 90 s frames in R filter. Total exposure time 22.5 minutes. In the picture, you can see several fragments of the comet nuclei. With that, the chance of this comet reaching high brightness sharply decreases.
