Shingles (GSI/QUB) OxQUB CV 0 1 OxQUB The spectrum resembles a blue continuum with faint H-alpha emission at rest wavelength reminiscent of a CV. The object was identified as a young, fast-evolving transient by the Fastfinder annotator (https://lasair-ztf.lsst.ac.uk/annotators/fastfinder/) on the Lasair ZTF alert broker. 2023TNSCR.997....1F
