So they are making this claim based on a 1100 year old observation compared to new intrumentation made just 14 years ago?

I think that explains it right there.

partly; but the reversals and major brightening are from comparing 20th century measurements; the stuff going back centuries is a different issue. The article is a typical Daily Mail jumble.

Yes it’s sort of like Global Warming. Trying to use modern measurements against estimated ancient measurements doesn’t necessarily work well. And it is Bush’s fault.

With what instrumentation. The first telescopes were made around 1608. The first photometers were made around 1861 and I imagine even those were not sensitive enough in a telescope for starlight measurements.

Comparisons were made by eye judging the light by comparing it to another one at least before 1608. So just how accurate that is the article does not say.

Must be another consequence of Global Warming...
