Rotationally modulated photometric variations in B supergiants?

Abstract

In this contribution, we present BRITE observations of the early-B supergiants $ε$ Ori and $κ$ Ori. We perform a preliminary analysis of the data acquired over the first two Orion observing runs. We evaluate whether they are compatible with co-rotating bright spots and discuss the challenges of such an approach.
