Return of the Clocked Burster: Exceptionally Short Recurrence Time in GS 1826−238

We report the discovery of an exceptionally short burst recurrence time in the well-known clocked burster GS 1826−238, observed with the CubeSat X-ray observatory NinjaSat. In 2025 May, GS 1826−238 underwent a soft-to-hard state transition for the first time in 10 yr. On June 23, NinjaSat began moni...
