are we still waiting on T Coronae Borealis to explode?

Yes, we're still waiting. While earlier predictions suggested the eruption of T Coronae Borealis (T CrB) could have happened by late 2024, it has not yet occurred. Astronomers still expect it to happen soon, though, and it remains a much-anticipated event.

Regarding a prediction for the end of this month (September 2025), there's no single, universally agreed-upon date. However, a prediction published in October 2024 suggested possible eruption dates, including November 10, 2025. Other forecasts based on the star's dimming and brightening patterns suggest a timeframe as broad as mid-2025 to late 2026.

The key takeaway from the latest observations is that the star is exhibiting behaviors similar to those seen before its 1946 outburst, such as a "pre-eruption dip" in brightness. This continues to lead astronomers to believe the nova is imminent on an astronomical timescale, even if the exact day, week, or even month is unknown.
