Description
T Coronae Borealis (T CrB), located at R.A. = $ 239.88^\circ $, Dec = $ 25.92^\circ $, is a famous recurrent novae, with two recorded fast nova eruptions in 1866 and 1946. In the 1946 eruption, the magnitude of T CrB peaks at $2.0^{\rm m}$, which is the brightest nova event from 1943–2022. Recently, Schaefer (2023)
observed the long-term monitored magnitude had a pre-eruption dip starting March/April 2023 and predicts that the eruption date would be $ 2024.4 +- 0.3 $ if the dip is similar to that in 1945. Maslennikova et al. (2023) predicts January 2024 with further 2023 photometry.
Inspiring by the previous observations of the very-high-energy gamma-rays from novae and the maximum particle energy estimated under physical conditions, taking the extreme brightness of its last eruption, the position close to the zenith of LHAASO and a distance of only $0.9 {\rm kpc}$ into consideration, we may have chance to observe the TeV emission from the next outburst of T CrB with the extraordinary sensitivity of LHAASO. We propose to monitor T CrB's 2024 outburst in TeV with LHAASO.
