April 4, 2012: Bram Ochsendorf (Leiden Observatory, Netherlands) has requested monitoring by AAVSO observers of the R CrB variable V854 Cen in support of observations to be made using the XSHOOTER instrument on the Very Large Telescope (VLT) of the European Southern Observatory's La Silla Paranal Observatory in Chile. Ochsendorf and colleagues have already observed V854 Cen at maximum and now need to observe it during a fading episode.
