ATLAS forced photometry server (Tonry et al., 2018; Heinze et al., 2018)
has quite a dense coverage of CTCV J2056-3014 from June 2017 to Dec. 2020
(with some data from 2015-2016 and the last observation currently on
2020-12-12). The light curve is showing long-term baseline variations with
the fading to the low state in August 2019. ATLAS light curve fills in the
1.5-year long gap in AAVSO observations. Minimum magnitude in 2019 was 18.2
in both cyan and orange filters. Outbursts occur in the high state (short
ones in 2017 and 2018, long one in 2020). See

Zoomed light curve of the 2020 superoutburst
http://scan.sai.msu.ru/~denis/J2056-3014-2020-LC.gif shows the
rebrigthening by about 2 magnitudes on Sep. 23-24 that was reported by
Taichi Kato in [vsnet-alert 24724] from Josch Hambsch observations.
