Galactic MMRD relation estimated using the sample of novae whose distance was measured with Gaia (Della Valle & Izzo 2020). Dashed lines correspond to a 2σ confidence region. Red data marks the position of V1369 Cen using the distance derived from the use of the DIB 862.1 nm and Gaia stars in the surroundings of V1369 Cen. Black data marks the position of V1369 Cen at a distance of 2.4 kpc (Mason et al. 2021), while green data represents the position of V1369 Cen assuming a Gaia-DR3 distance (Schaefer 2022).
