Homer Dávila Gutierrez, director of SKYCR.ORG, has identified a gravitational arc candidate in the galaxy cluster MACS J0308.9+2645 from public data from the James Webb Space Telescope. The object had not been previously reported and is located at a photometric redshift close to 4.4. The preprint is available on arXiv and the manuscript is under review in Publications of the Astronomical Society of Japan.
