**For simplicity, we'll update AT 2023aecs's host redshift to that reported in AT 2022acfu's discovery report (z=0.949)

Host galaxy redshift update

AT 2022acfu (https://www.wis-tns.org/object/2022acfu) also exploded in AT 2023aecs's host galaxy, and AT 2022acfu's discovery report quotes a host redshift of z=0.949. AT 2023aecs's initial report states a host galaxy redshift of z=0.89, which is a photometric redshift. Searching AT 2023aecs's coordinates on the NASA/IPAC Extragalactic Database (NED) with a maximum separation of 0.02 arcmin yields one result: HLS J001422.7-302350, otherwise known as UNCOVER DR2 16363. The NED webpage reports a spec-z of 0.944 for this host galaxy. For simplicity, we'll update AT 2023aecs's host redshift to that reported in AT 2022acfu's discovery report (z=0.944)
