Visual light curve of R71 using data from ASAS (triangles; Pojmanski 1997) and AAVSO (squares; www.aavso.org). Epochs at which spectroscopic observations with UVES, FEROS, and X-shooter are available are indicated. The epochs of WISE and VISIR mid-infrared imaging observations are also indicated. An oscillation in the light curve is clearly apparent since 2010. Variations with a shorter timescale can be seen in 2007 and 2008 during the onset of the outburst.
