C. DeCoursey, on behalf of the MAGNIF collaboration report/s the discovery of a new astronomical transient.
IAU Designation: AT 2023aedf
Coordinates (J2000): RA = 00:14:10.957 (3.545656) DEC = -30:20:15.91 (-30.337753)
Discovery date: 2023-10-30 00:00:00.000 (JD=2460247.5)
Potential host galaxy: A2744+3.54561-30.33772
Host redshift: 1.62
Remarks: Host magnification is mu = 1.299 according to UNCOVER DR2
Photometry
Discovery (first detection):
Discovery date: 2023-10-30 00:00:00.000
Flux: 26.952 ABMag
Filter: Other-
Instrument: NIRCam
Telescope: James Webb Space Telescope
Remarks: Reported photometry comes from averaging F182M and F210M photometric measurements. We performed this averaging to create a pseudo-F200W measurement to compare against UNCOVER's F200W photometry. Filter is JWST - NIRCam-F182M/F210M.
Last non-detection:
Archival info: Other
Remarks: This source was not detected in the Ultra-deep NIRCam and NIRSpec Observations Before the Epoch of Reionization images (UNCOVER; Cycle 1, GO 2561; https://jwst-uncover.github.io/).
