Light curve of St 2-22 with the ongoing outburst. Green and brown dots correspond to the V- and I_c-band data, respectively, acquired at the Kleinkaroo Observatory, whereas the ASAS and ASAS-SN V- and g-band, as well as OGLE I-band data, are plotted as black points. The zero-point of the OGLE photometry is shifted by −0.38 mag. Arrows above the light curves mark the HRS and FEROS observations with (blue) and without (red) jet detection, while those below mark the times of periastron passage (black) and inferior conjunction (magenta) according to the eccentric orbit solution (Table 3).
