Here we present a multiwavelength overview of Swift J023017.0+283603 (hereafter Swift J0230+28), a source from which repeating and quasi-periodic X-ray flares are emitted from the nucleus of a previously unremarkable galaxy at ∼165 Mpc. Others have recurrence times as long as hundreds to a thousand days and are called repeating nuclear transients. Some have recurrence times as short as a few hours to a day and are known as quasi-periodic X-ray eruption (QPE) sources. Galactic nuclei showing recurrent phases of activity and quiescence have recently been discovered. X-ray eruptions every 22 days from the nucleus of a nearby galaxy
