Blaze Star 2026: T Coronae Borealis Nova & June 25 India View Guide

TL;DR: The Blaze Star 2026 (officially known as the T Coronae Borealis nova 2026) is a highly anticipated astronomical event where a dead star will temporarily ignite, creating a "new star 2026" in our night sky. Expected to reach magnitude +2, this once-in-a-lifetime spectacle will be visible to the naked eye. Read on to discover exactly how to see the Blaze Star, including detailed India viewing times and star-hopping guides.

Current Status: As of June 19, 2026, T CrB has NOT yet erupted and remains near its baseline brightness of magnitude 10. However, astronomers are on high alert. We will update this post the moment the eruption is confirmed by the AAVSO live brightness tracker.

What is the Blaze Star (T Coronae Borealis) & How Does It Work?

Key facts about this cosmic phenomenon include:

• The System – Located ~3,000 light-years away, T CrB is a binary system consisting of a dense white dwarf and a bloated red giant locked in a 227.55-day orbit.
• The Mechanism – The white dwarf siphons hydrogen from its companion until a thermonuclear runaway occurs on its surface. It is a recurrent nova 2026 event, not a supernova, meaning the star is NOT destroyed in the process.
• Historical Eruptions – The last confirmed eruptions were in 1866 and 1946, with possible historical sightings recorded by observers in 1217 and 1787.

According to NASA Goddard, these recurrent novae are incredibly rare, making this a generational skywatching opportunity. But the burning question remains: when will T Coronae Borealis explode?

When will it erupt? (The June 25, 2026 prediction)

Important dates to track for the T CrB nova date:

• June 25, 2026 – This is the current statistical prediction calculated by Jean Schneider at the Paris Observatory (published in the Research Notes of the AAS, 2024, DOI 10.3847/2515-5172/ad8bba). Note that this is a statistical estimate with NO guarantee.
• Lapsed Dates – Previous models suggested March 27, 2025, and Nov 10, 2025, both of which passed without an eruption.
• Fallback Date – If June passes quietly, the next statistical target is February 8, 2027.

How bright will it get?

When the eruption begins, T CrB will brighten rapidly from magnitude 10 to approximately magnitude +2 within hours—making it roughly as bright as Polaris, the North Star. Do not expect a dramatic fireball: it will simply appear as a modest, 'new' point of light in the Northern Crown constellation. It should remain visible to the naked eye for several days, and then fade into a binocular target for about a week.

This makes it an excellent addition to your summer observing schedule. If you are already planning your nights for the upcoming Perseid Meteor Shower 2026 or tracking our Aug 12 total solar eclipse update, keep a close watch on Corona Borealis.

How to see the Blaze Star from India (IST timings & star-hop)

Corona Borealis how to find: The Northern Crown constellation is exceptionally well-placed for observers in India. From regions like Gujarat (~22°N), the constellation passes nearly overhead, reaching a transit altitude of ~86°. For optimal Blaze Star IST viewings, look up on late June evenings around 10:25 pm IST, or in mid-July around 9:05 pm IST when it sits high near the zenith. To find it, star-hop from the Saptarishi (Big Dipper) handle in an arc to Arcturus (Swati), then draw a line toward Vega (Abhijit). The distinct C-shape of the Northern Crown sits between them, with T CrB located just ~1° from the star Epsilon CrB.
