At the beginning of 2004 a photometric campaign started from the South African Astronomical Observatory (SAAO), dedicated to the observation of southern Blazhko stars. This campaign allowed us to select the best targets for a spectroscopic study. In the summer of 2005 (July-September) a big simultaneous photometric campaign was carried out from SAAO (South Africa) and SSO (Siding Spring Observatory, Australia).
Some of the data resulting from this campaign can be found here.

In the summer of 2005 we organized a simultaneous campaign at SAAO (South Africa) and SSO (Australia).
Colour coding:
orange SAAO
green SSO
yellow SAAO & SSO
From SSO the data were gathered by
PL: Patrick Lenz,
LS: Lukas Schmitzberger,
BS: Bob Shobbrook.
The Blazhko effect in SS For, as observed in the course of two weeks from SAAO.
Observations by Elisabeth Guggenberger and Thebe Medupe; figure by Elisabeth Guggenberger.
The changing light curve of UV Oct folded with the pulsation period.
Coming soon: Publications based on the southern Blazhko star data are in preparation.
