Christa DeCoursey, on behalf of JADES report/s the discovery of a new astronomical transient.

IAU Designation: AT 2022aeix
Discoverer internal name: jades-gs-2022f
Coordinates (J2000): RA = 03:32:27.153 (53.113138) DEC = -27:51:25.77 (-27.857158)
Discovery date: 2022-10-07 00:00:00.000 (JD=2459859.5)


Remarks: We report the detection of a transient in the GOODS-S field, observed by JWST NIRCam on October 7th, 2022. The candidate does not appear in the GOODS-S HST mosaic images (v2.0) distributed by the Hubble Legacy Fields (HLF) project (https://archive.stsci.edu/prepds/hlf), confirming its transient nature. It lies at RA 03:32:27.153, DEC -27:51:25.77, and it does not appear to have a host galaxy. We performed aperture photometry on the transient and measured the following AB magnitudes: F090W = 26.07 ± 0.01, F115W = 26.08 ± 0.01, F150W = 26.17 ± 0.01, F200W = 26.26 ± 0.02, F277W = 26.82 ± 0.02, F356W = 27.17 ± 0.02, F410M = 27.28 ± 0.04, and F444W = 27.53 ± 0.04.
