Kp needed comes from the NOAA Space Weather Scales, which give latitudes for Kp 6–9. Values for places north of about 55° geomagnetic latitude (including Alaska) are our extrapolation. NOAA notes that even at Kp 0 the edge of the auroral oval sits near 66° geomagnetic latitude, so interior Alaska can see aurora on quiet nights. How we calculate this.
