As an addition to and clarification of ATel #2036, we point out that the oscillations with period ~45d were first presented and discussed by Reig et al. (2008, A&A 485, 797). At the time of publication, the source had not yet clearly transitioned into the ~72d period oscillatory stage. The intent of ATel #2036 was to present the changing periodicity, and not the discovery of oscillations.
