IAU Designation: AT 2024kmd
Discoverer internal name: ZTF24aaqozyb
Coordinates (J2000): RA = 14:50:16.103 (222.567096) DEC = +69:44:29.37 (69.741492)
Discovery date: 2024-06-05 05:33:01.000 (JD=2460466.7312616)


Remarks: SN candidate discovered using the LSST/ZTF Lasair and ALeRCE brokers and the new experimental deep and high-cadence ZTF survey described in Ho et al. (AstroNote 2024-135), with several ZTF g-band detections on 2024-06-05 and 2024-06-06. The transient is located close to two red galaxies with large DESI Legacy Imaging Surveys photometric redshifts, photo-z = 0.735-0.820 (Duncan 2022). The ZTF light curve is available at the LSST/ZTF brokers, e.g.: https://lasair-ztf.lsst.ac.uk/objects/ZTF24aaqozyb/ https://alerce.online/object/ZTF24aaqozyb
