Re: AT2024epj - A mag 10 transient in/near the LMC

Good result despite the low luminosity

Very fast nova.
Expansion velocity 4900-5100 km/s measured on H alpha and H beta.

Re: Nova Oph 2024

Impressive! Very high velocity.
Thus nova event produced by a high mass white dwarf, small mass of the accreted envelop and large part of the envelop ejected.
Congratulations.

Re: T CrB before its new nova event

The new season of observations after the solar conjunction is begining. Since the detection of the end of the high state (2015-2023), T CrB evolves in the same way as before the high state with orbital variations of the photometry and spectroscopic appearence.
