Example of a possible configuration that gave rise to SN 2022lxg. We envisage a disc-like CSM (with a potentially azimuthally asymmetric density distribution) with the line-of-sight at a low inclination. (a) Before the explosion, we suggest that the CSM closest to the progenitor is denser and could have been formed by material transferred from a donor combined with stellar winds. (b) The fast-moving ejecta crash into the inner dense CSM giving rise to the observed flash-ionisation features and the luminous peak. Within ∼10−15 d this denser CSM is completely swept-up by the ejecta. (c) Between 10−35 d, the ejecta encounter the outer, hydrogen-rich, disc-like CSM and encompass it. Broad lines from the free-expanding, cooling ejecta emerge while the radius of the composite photoshpere plateaus. (d) After ∼35 d, the photosphere recedes, the optical depth of the ejecta drops, and the power comes from the interaction. Narrower Hα emerges and dominates the spectrum.
