QS Ser is one of the several dozens of false variables introduced by the HIP cataloge. The false ~ 1/4 mag "variations" in the HIP data are due to the close companion (the mag differences of the HIP obs show exactly the flux differences between the brighter star alone and both components combined). The false ~ 1 mag "jumps" in the HIP obs doublets with ~ 20 min spacings are due to how the star transited across the coded mask in front of the detector combined with the spinning of the spacecraft and its orbit.
