re Kp and Bz; without wanting to get too technical, they are measures of how the Earth's magnetic field is being disturbed by charged particles ejected by the Sun. Kp of 5 and above is highly disturbed and is indicative of unusually high levels of solar particles passing by. Bz pointing south allows these charged particles to follow Earth's magnetic field lines towards the poles - a condition very conducive to auroras.
