Ajeesh PU report/s the discovery of a new astronomical transient.
IAU Designation: AT 2026ogc
Discoverer internal name: ZTF20abewfff
Coordinates (J2000): RA = 19:22:51.059 (290.712746) DEC = +13:14:20.37 (13.238992)
Discovery date: 2026-05-14 10:17:24.000 (JD=2461174.92875)
Remarks: ZTF20abewfff is an optical transient candidate from ZTF/ALeRCE. ALeRCE broker classification flags it as SLSN-like, with detections from 2026-05-14 through 2026-06-05 UTC. Authenticated TNS API check found no existing TNS match, and SkyBoT found no known Solar System object match. Stamp classifier has a VS-like warning, so this is submitted as a candidate pending independent review and follow-up confirmation.
Photometry
Discovery (first detection):
Discovery date: 2026-05-14 10:17:24.000
Flux: 19.815 ABMag
Filter: i-Sloan
Instrument: ZTF-Cam
Telescope: Palomar 1.2m Oschin
Remarks: First ZTF alert detection. ALeRCE corrected magnitude for this point is i=18.436, but raw alert magpsf is reported here.
Last non-detection:
Last non-detection date: 2026-05-13 10:51:50
Limiting flux: 20.6267 ABMag
Filter: r-Sloan
Instrument: ZTF-Cam
Telescope: Palomar 1.2m Oschin
Remarks: Last pre-discovery non-detection from ALeRCE/ZTF light curve.
Archival info: Other
Remarks: No archival image uploaded. ALeRCE/ZTF includes 51 pre-discovery non-detections; best pre-discovery limiting magnitude is 20.7057.
