Description
T Coronae Borealis is a recurrent nova system that erupts approximately every 80 years. Given that the last outburst occurred in 1946 and recent unusual activity, including a "pre-eruption dip" similar to that seen before the previous event, a new eruption is thought to be imminent, sparking intense interest. We present recent photometry and spectroscopy covering this dip and the subsequent recovery. While the optical spectrum typically displays a hot continuum from the white dwarf and accretion disk alongside a red giant secondary, we found that the hot component vanished during the dip. It has since recovered, showing high levels of activity. This ongoing observational campaign of T CrB involves observers from all over the world and will provide the most comprehensive coverage of a nova system leading up to an eruption.
