IAU Designation: AT 2023vnw
Discoverer internal name: jades-gs-3215a
Coordinates (J2000): RA = 03:32:15.166 (53.063191) DEC = -27:51:26.92 (-27.857477)
Discovery date: 2023-10-17 00:00:00.000 (JD=2460234.5)
Potential host galaxy: JADES-GS+53.06318-27.85748
Host redshift: 4.37
Remarks: Although the transient remains undetected in the F182M or F210M band, we confirm that the transient is detected in the F300M band. The F300M photometry is a subject of future work because there is no F300M data that can be used to produce a difference image. Likely host redshift is z_phot = 4.37 ± 0.03.
