Angelina Shorohova on behalf of the SNAD team et al. report/s the discovery of a new astronomical transient.
IAU Designation: AT 2018mtx
Discoverer internal name: SNAD334
Coordinates (J2000): RA = 14:56:36.252 (224.15105) DEC = +44:18:20.20 (44.30561)
Discovery date: 2018-06-17 07:48:22.000 (JD=2458286.8252546)
Remarks: Transient identified by Pineforest (https://arxiv.org/abs/2410.17142). See more info at:https://ztf.snad.space/view/759203400003697. There is no ZTF Alert ID for this object (i.e., not in the alert stream), so we report the internal SNAD Object ID instead. The internal SNAD Object ID is SNAD334.
Photometry
Discovery (first detection):
Discovery date: 2018-06-17 07:48:22.000
Flux: 21.15 ABMag
Filter: r-ZTF
Instrument: ZTF-Cam
Telescope: Palomar 1.2m Oschin
Remarks: For the first photometric point reference magnitude is 21.732 mag. ZTF DR OID 759203400003697 (zr). No ZTF Alert ID found, so we report the internal SNAD Object ID instead. The internal SNAD Object ID is SNAD334.
Last non-detection:
