An optical transient detected by ATLAS and ZTF that has just been confirmed to be rapidly evolving in all `gri` bands and has a spectrum consistent with the kilonova AT2017gfo which was associated to the famous binary neutron star merger GW 170817.  
Details: [AstroNote 2024-92 | Transient Name Server](https://www.wis-tns.org/astronotes/astronote/2024-92)

Update: a spectrum taken at Keck ressembles that of a type IIb supernova about two days before peak flux: [AstroNote 2024-94 | Transient Name Server](https://www.wis-tns.org/astronotes/astronote/2024-94) While less exciting than a kilonova, this remains a valid target for the next days and week(s).

SN 2024ggi is a fast rising optical transient detected by ATLAS for which the pre-explosion star has been detected in archival HST images. Spectral classification as a young type-II SN. Unfortunately at a declination of -32deg…
