Tonight! Forecast of KP 7. "The Kp index is a scale that measures the strength of geomagnetic disturbances, ranging from 0 to 9, with higher numbers indicating more significant activity." If you want the best views, head somewhere without light pollution. Hopefully no cloud cover either. Best time to view? When it's dark. 9pm to 1am has often been a good time but it can vary. via swpc.noaa.gov #Calgary #Edmonton #Alberta #Banff #Canmore #RedDeer #Canada
