Light curve of GDS J1613117−503040 from the Bochum survey (Hackstein et al. 2015). A fast photometric decline of 3 mag is observable around JD∼2456500 days in both the r and i bands. This star is surrounded by two distinct circumstellar dust shells and was therefore not selected by our IR photometric selection criteria. We consider it as an RCB candidate that needs a spectroscopic follow-up for confirmation.
