After 15 years from the first observed outburst the NS-LMXB Transient XTE J1701-462 turned on again on September 6 (Iwakiri et al. 2022 ATel 15592). The MAXI light curve indicates that it is likely to reach the peak in luminosity within a week and its luminosity is approaching 500mCrab in the 2-10 keV band.Among its class XTE J1701-462 is a unique target: it is the only known NS to exhibit (Lin et al. 2009) all the NS-LMXB spectral substates from Cyg X-2-like Z class up to Sco X-1-like Z and back down to bright atoll and island atoll states during its 2006 outburst evolution. We request INTEGRAL observations of XTE J1701-462 coordinated with the approved IXPE TOO programme foreseen on Sept. 29 and Oct. 9 2022. [truncated! Please see actual data for full text]
