I don't know the reason for the vast discrepancy in distance. As close as 427 Lty to 700 lty. That's quite a gap.

The massive dip in brightness is almost certainly a notable curiosity, and not any portend to an immediate ( from our perspective ) onset of any super nova. It is, however, a bit of info that future astronomers hopefully will be able to access when it finally does explode. Perhaps 100's or 1000's of years from now.

I agree.

I'm wondering why the search engine results came up with 700, which is not even rounded from the 642 figure.
And 427 is even further out of range.

Do you know why there is such discrepancy?

Yes, interesting. And thanks for the head's up. If it had expired, folk would be whining that nobody told them beforehand.

Short and simple, no imminent super nova.

Dammit.

Still, interesting to watch a red giant go through its old age changes. Even if we're not gonna witness anything truly spectacular from it.

As you were.
