Following the posting on the Central Bureau's Transient Object Confirmation Page regarding a possible nova in Tau (TOCP Designation: TCP PNV J03555441+2009522), we performed follow-up observations of this object using a 0.35-m f/3.0 reflector telescope equipped with a CMOS camera, located in Australia, near Moorook, and operated by SPACEFLUX company (MPC Code Q22). In images taken on August 27.84, 2025, we confirm the presence of an optical counterpart with an unfiltered CMOS magnitude of approximately +5.7, at coordinates R.A. = 03 55 54.59, Decl. = +20 09 50.3 (equinox 2000.0; astrometry based on Gaia DR2 catalogue reference stars).

Although its reported magnitude is faint, the position of this PNV coincides with Uranus. We retract this post about PNV and apologize. --- Isao Endoh & Seiichiro Naito (NAOJ)
