It was discovered in NIRCam observations of GO Program 5398 (PI: Jeyhan Kartaltepe) using SFFT image subtraction code. We used archival NIRCam data provided by ERS Program 1345 (CEERS; PI: Steven L. Finkelstein) as reference. The transient search is part of JWST Archival Research Program 5965 (JCAST; PIs: Lei Hu & Lifan Wang). 2025TNSTR3600....1H N
