How to choose the best viewing window
Start with astronomical night: aurora is easiest to see when the Sun is well below the horizon.
Check moonlight: a bright Moon can wash out faint aurora, especially near cities.
Watch Kp and Bz together: stronger Kp helps, but sustained southward Bz often matters more for sudden activity.
Pick a dark horizon: face north in the Northern Hemisphere and south in the Southern Hemisphere.
