Cycles 19 145 and 19 146 (Obs2) in soft (0.2–1.0 keV) X-rays (top panel). Bright phase dips occurring at phase 0.81−0.83 and pre-eclipse dips beginning at about phase 0.9 and leading into ingress are visible. The middle and bottom panels show hardness ratios (Eq. (1)) for these two cycles. The two dips are much harder than the rest of the bright phase. For clarity the eclipses and faint phases are not plotted in the hardness ratio panels. The third cycle of Obs2 is omitted because it is severely affected by data gaps.
