      So, if we’re about to see it doesn’t that mean that it actually exploded about 3000 years ago?

      From wikipedia: “Even when at peak magnitude of 2.5, this recurrent nova is dimmer than about 120 brightest stars in the night sky.”

      But how do they know it will “explode”? I only have a passing knowledge of this kind of stuff but isn’t predicting a supernova almost impossible given our current understanding?

      Soon on astronomical and cosmological scales could mean “tomorrow” or it could mean “500 years from now”.

      This title and article do a terrible job of explaining anything at all, so for those confused about when this will occur in the context of 3000 light years:

      Blaze Star is a recurrant nova that flares every 80 years or so. Last observed in 1946. It is this repeated activity that allows astronomers to predict that we’ll see it again soon.

      The prediction for the next flare is between now and early 2027. And it is likely to go unnoticed by most people.

      For how long will this new, slightly less dim dot be visible? Seconds,minutes, less than a second?

      Is “will explode” the right words to describe something that happened 3k yrs ago?

      Blaze Starr already happened once this lifetime though, and she had an affair with Louisiana governor Earl Long in the 1950s.
