IAU Designation: AT 2023jym
Discoverer internal name: jades-gn-2023q
Coordinates (J2000): RA = 12:37:02.722 (189.261342) DEC = +62:09:47.85 (62.163292)
Discovery date: 2023-04-05 00:00:00.000 (JD=2460039.5)
Remarks: We report the detection of a transient in the GOODS-N field, observed by JWST NIRCam on April 5th, 2023. The candidate does not appear in the GOODS-N HST mosaic images (v2.5) distributed by the Hubble Legacy Fields (HLF) project (https://archive.stsci.edu/prepds/hlf), confirming its transient nature. The transient lies at RA 12:37:02.722, DEC +62:09:47.85, and it has no clear host galaxy. We performed aperture photometry on the transient and measured the following AB magnitudes: F090W = 27.28 ± 0.04, F115W = 26.94 ± 0.02, F150W = 26.94 ± 0.02, F200W = 26.69 ± 0.02, F277W = 27.22 ± 0.02, F335M = 27.45 ± 0.02, F356W = 27.48 ± 0.02, F410M = 27.61 ± 0.06, and F444W = 27.61 ± 0.04.
