  We present our analysis of photometric data in the Johnson B and V filter of
the southern Blazhko star SS For. In parallel, we analyzed the V observations
obtained with the ASAS-3 photometry of the star gathered between 2000 and 2008.
In the frequency spectra resulting from a Fourier analysis of our data, the
triplet structure is detectable up to high order, both in the B and V data.
Moreover, we find evidence for quintuplet components. We confirm from our data
that the modulation components decrease less steeply than the harmonics of the
main frequency. We derived the variations of the Fourier parameters quantifying
the light curve shape over the Blazhko cycle. There is good agreement between
the spectroscopic abundance and the metallicity determined from the Fourier
parameters of the average light curve. SS For is peculiar as a Blazhko star
because of its strong variations around minimum light.
