- Abstract
High-precision multisite photometry was used for a detailed investigation of the bump occurring before minimum light in the light curves of the two RRab Blazhko stars RR Lyr and SS For. For both stars, the phase of the bump was found to be variable with a period equal to the Blazhko period, with the bump occurring at an earlier phase around Blazhko minimum and at higher values during maximum.
