Table 1: Basic properties of comet C/2004 Q2 (Machholz).
Table 2: Observational log. For each night, the number of observations is given for each filter U, B and I. Also the heliocentric ( $r_{\rm h}$ ) and geocentric ( $\Delta$ ) distances are given (in AU, at 0:00 UT), together with the correction factor $f_{\rm a}$ (see Eq. (2) in Sect. 4.2).
Table 3: Summary of the frequency analysis results. Three different methods were used to get rid of the brightness increase during two nights of our observational run (12, 13 and 13, 14 January); see Sect. 5.2 for more details.
