We found the transient, which should have a magnification of ~4, in imaging taken by the Hubble Space Telescope SNAP GO-16279 program, which is searching for microlensing events of high-redshift magnified stars. In a visit to the field on May 30th, we detect a source with F110W = 25.8+-0.3 mag, with no detection in F606W. No transient is detected in imaging from a previous visit to the field by the program on May 18th. The SN may reappear in ~9.5 years in a pair of highly magnified images of its host galaxy, if it is located in the multiply imaged region of the galaxy. An HST Director’s Discretionary program has been approved to measure its light curve, and acquire WFC IF G102 grism spectroscopy. If a Type Ia SN with minimal extinction, it should reach a peak magnitude of F110W~23.8 magnitudes in early July. | 2022TNSTR1767....1K | N |
