Observations of CzeV404 Her obtained in the ASAS-SN project, at the BSO, and at Ondřejov Observatory. The V-band data from the ASAS-SN project were shifted by +0.4 mag, and the C-band data of Ondřejov and BSO were shifted by +0.2 mag. Black triangles mark superoutbursts detected by these observations. Vertical full lines mark the observation epochs presented in Fig. 7. The same colour is used for the same observation time. Vertical dashed lines mark the time of spectroscopic observations listed in Table 2.
