Aims. We study the geometry of the circumstellar environment of the B[e] supergiant star GG Car. Methods. We present observations acquired using the IAGPOL imaging polarimeter in combination with the Eucalyptus-IFU spectrograph to obtain spectropolarimetric measurements of GG Car across Hα at two epochs. Polarization effects along the emission line are analysed using the Q−U diagram. In particular, the polarization position angle (PA) obtained using the line effect is able to constrain the symmetry axis of the disk/envelope. Results. By analysing the fluxes, GG Car shows an increase in its double-peaked Hα line emission relative to the continuum within the interval of our measurements (∼43 days). The depolarization line effect around Hα is evident in the Q−U diagram for both epochs, confirming that light from the system is intrinsically polarized. A rotation of the PA along Hα is also observed, indicating a counterclockwise rotating disk. The intrinsic PA calculated using the line effect (∼85 • ) is consistent between our two epochs, suggesting a clearly defined symmetry axis of the disk.

MANIFEST is a multi-object fibre facility for the Giant Magellan Telescope that uses 'Starbug' robots to accurately position fibre units across the telescope's focal plane. MANIFEST, when coupled to the telescope's planned seeinglimited instruments, offers access to larger fields of view; higher multiplex gains; versatile focal plane reformatting of the focal plane via integral-field-units; image-slicers; and in some cases higher spatial and spectral resolution. The TAIPAN instrument on the UK Schmidt Telescope is now close to science verification which will demonstrate the feasibility of the Starbug concept. We are now moving into the conceptual development phase for MANIFEST, with a focus on developing interfaces for the telescope and for the instruments.
