Abstract
We review the status of photoelectric and visual monitoring of key objects among southern massive stars,
specifically the LBVs/hypergiants HD 6884 (R 40), j Car, AG Car, HDE 326823, HDE 269006 (R 71), and
WR stars HD 5980, WR 40. Data have been obtained over the last two decades in the framework of the Long­
term Photometry of Variables project and through visual monitoring from New Zealand. Unpublished light
curves are presented and novel insights on the light variability of these most enigmatic stars are discussed.
Keywords: LBVs, WR stars, HDE 326823, j Car, AG Car, R 71, R 40, HD 5980, WR 40
