Oh. It's brightening..!? This is within normal ranges for it, however. Guess we'll see...

(Still dim, but it was magnitude 11.1 a week or two ago. Fingers crossed 🤞)

Thinking of the Blaze Star, a recurrent nova coming soon, I wonder how many historic moments were marked by such events.

Soon, a 'new' star will shine for 3 days before vanishing. This nova repeats every ~80 years, and recent observations show it's imminent.

A 'new star' could appear in the sky any night now. Here's how to see the Blaze Star ignite.

The "Blaze Star" T Coronae Borealis will erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.

> But every 80 years or so, exchanges between its two stars, which are locked in a deadly embrace, spark a runaway nuclear explosion.

Huge star explosion to appear in sky in once-in-a-lifetime event

Sometime between now and September, a massive explosion 3,000 light years from Earth will flare up in the night sky, giving amateur astronomers a once-in-a-lifetime chance to witness this space oddity.
