X-ray luminosity of L 98-59 in the band 0.3–10 keV vs. time. A cycle of about 1.95 years is shown as a sinusoidal dashed line. We made a rough estimate of the period by assuming that the minimum of the sinusoid is the value recorded in October 2024 and that its mean is equal to the value measured in February 2025.
