That's a great point. Although the north magnetic pole has wandered quite a lot during the past 100 years, the geomagnetic pole has stayed relatively still. However, 3000 years is still a long time so it's definitely possible it was way closer to the geographic poles.
I didn't find any information about its location before 1900. The magnetic pole (not geomagnetic pole) was actually even more tilted towards North America at around 1600 than now

Ancient China (that is, pre-Imperial China), not so much. China had yet to expand far beyond the "Central Plain" at this point in time (early Zhou dynasty, aka Western Zhou period).

Was it so heavily tilted towards North America in 900 BC?

Aurora ovals are centered around geomagnetic poles and not geographic poles. The northern one is tilted heavily towards North America so the chance to see auroras at 53° N China is the same as in Indianapolis (39.7° N)

I just looked it up, the northernmost point in China that I could find is at roughly the same latitude as Edmonton, Alberta, Canada.

China can get pretty far North.

The coastline of England has changed over the centuries, especially in the east.

That's so cool, I didn't know it could have been spotted there! Thank you for sharing!
