| dc.description.abstract | XRISM/Xtend Transient Search (XTS) detected an increase in X-ray intensity from an X-ray source XRISM J1717-3717 on 2025-02-28 TT. The source position is determined to be (R.A., Dec.) = (259.347, -37.28648), with a systematic error of ∼ 40 arcsec. A plausible counterpart is 2SXPS J171724.0-371717, which is located ∼ 11 arcsec apart from the position of XRISM J1717-3717. The X-ray flux in the 0.4 – 10 keV band increased logarithmically from 2 × 10⁻¹² erg s⁻¹ cm⁻² to 7 × 10⁻¹² erg s⁻¹ cm⁻² between 2025-02-28 13:30 TT and 2025-02-28 22:30 TT, and remained at the same level until 2025-03-01 15:00 TT. We estimated the systematic error for the source position from the separations between the detected sources with the corresponding counterparts in the same field of view. | |
