The observing date is presented in the form DD.MM.YY; the heliocentric Julian date (HJD) is given for the middle point of either the exposure or the whole observing time during the night (in case of multiple observations); the phase of the activity cycle is calculated according to the ephemeris of Miroshnichenko et al. (1998); N is the number of spectra obtained during the night; EW is the H$\alpha $ line equivalent width; the observatory where the spectra were obtained is indicated in the last column.
