Estimated deviations in the horizontal magnetic field and the declination at Alaska and West Siberia due to a substorm electrojet.

Hdisturbance (nT)
Location/parameter Hnominal (nT) D′ (°) Hmeasured (nT) ΔH (nT) (±) ΔD (°)
Alaska 10,000 2 9500 −500 0.1
Alaska* 10,000 40 9622 −378 1.9
West Siberia* 5000 2 4500 −500 0.2
West Siberia 5000 40 4628 −372 4.0

The value D′ is swapped between the two locations.
