Discovery (first detection):
Discovery date: 2019-02-26 08:59:16
Flux: 20.86 ABMag
Filter: g-ZTF
Instrument: ZTF-Cam
Telescope: Palomar 1.2m Oschin

Last non-detection:
Archival info: Other
Remarks: This is a slow-rising object with a discovery magnitude close to the survey limit, so individual-epoch nondetections are not meaningful. It shows no history of variability in the survey prior to the initial detection. A nearby faint source (the probable host galaxy) catalogued in ZTF and PS1 reference imaging is significantly astrometrically offset.
