There's a wiki error on Aemond Targaryen's page.
It says "on the same day they battled and died, Queen Helaena Targaryen committed suicide at sunset the capital."
The sources listed (Fire & Blood, The Dying of the Dragons - Rhaenyra Overthrown and The World of Ice & Fire, The Targaryen Kings: Aegon II) for this statement do not say this nor can it be inferred.
F&B, TWOIAF, and TPATQ doesn't have a day of death for Helaena nor does it state she died the same day as Daemon and Aemond. Neither does Rise of the Dragon which explicitly puts her death days after Daemon's death.
Her own wiki page just lists 130 AC as her time of death and no specific date.
There's nothing ruling it out but there's nothing validating it in any source. It states in every source that she died the same day as men abandoning Rhaenyra's cause, not that she died the same day as Daemon and Aemond.
