Then it hit me, could this actually be the effects of the aurora?

google for "Space Weather Effects on GPS"

there's a presentaton by Thomas Bogdan at the Space Weather Prediction
Center that gives you some numbers to work with.

10s of meters effects aren't unusual.

You might try compressing the file with something like 7z, or zip.
That should reduce it about 10x in size.
