ASASSN-V J060000.76-310027.8 was originally reported in ATel #13346 as a rapidly fading source that was previously quiescent in the previous six years of ASAS-SN photometry. From the most recent ASAS-SN image-subtraction photometry the source reached a minimum magnitude of g~15.0 on UT 2019-12-11.03. The source then brightened to g~14.5 on UT 2019-12-16.37 where it reached a local maximum and then began a possible second dimming event. The source has since faded to g~14.6 on UT 2019-12-18.38.
Buckley et al. (ATel #13349) reported spectroscopy for this object obtained at the South African Astronomical Observatory. They conclude that ASASSN-V J060000.76-310027.83 is an early K-type star.
Follow-up observations of this very unusual object are strongly encouraged.
