Centaurus X-3 (4U 1118-60) is an X-ray pulsar with a pulse period of 4.80461 s (±0.00006) and an orbital period of ~2.1 days (Tomar et al. 2021, Bildsten et al. 1997). Recently, the source went through a flaring activity at the end of February 2021 (ATel #14417).
We report enhanced activity from the pulsar as detected by Fermi/GBM (12-25 keV). The pulsed flux in hard X-ray has started to increase from MJD 59287 (2021-03-14) and reached 0.472±0.017 keV cm-2 s-1 on MJD 59293 (2021-03-20).
We encourage further multi-wavelength follow-up observations.
