It brightened up to 12-13 mag from 2018 to 2019. Now it is fading. It has already faded down to 17.0 mag (June 24, P. Camilleri, H. Williams, M. Al-Bussadi). In the Southern Hemisphere, it stays observable in good condition for a long time. It will never be observable after this in the Northern Hemisphere.

Sam Deen pointed out that it brightened in outburst twice in 2017 and 2019. It was observed at 20-21 mag in 2017. Then it became fainter than 22.9 mag in 2018 summer (Aug. 29, Sam Deen). However, it brightened up to 17.2 mag in 2019 spring (Mar. 25, B. T. Bolin). Then it is fading again after that. Now it is 19.9 mag (May 29, Toshihiko Ikemura, Hirohisa Sato). It is predicted to stay observable at 18 mag for a long time from 2019 to 2021. But actually, it is much fainter than this ephemeris.

Fragment of C/1844 Y1 (Great Comet). It brightened up to 7.0 mag in late March ((Mar. 30, Charles S. Morris). But the nucleus was split into some fragments, and it faded out after that. It was 9.1 mag in mid May (May 17, Sandor Szabo). It approached to Sun down to 0.25 a.u. on May 31. In the Northern Hemisphere, it is not observable after this. In the Southern Hemisphere, it is appearing in the morning sky, but it locates extremely low.
