The Astrophysics Division of INPE, in collaboration with the Laboratório Nacional de Astrofísica (LNA), built an optical astronomical instrument as a demand of the scientific interest of many Brazilian research groups. SPARC4 - Simultaneous Polarimeter and Rapid Camera in Four bands - combines in one instrument: (i) simultaneous imaging in four broadbands; (ii) photometric and polarimetric modes; (iii) sub-second time-resolution in photometric mode and excellent time resolution in polarimetric mode. This combination makes SPARC4 a unique facility among ground-based optical observatories. It is installed at the 1.6-m telescope of Observatório do Pico do Dias/LNA, in Brazil.
