Furthermore, I cannot recommend highly enough to anyone whom wishes to see the aurora for yourself--from experience I can highly suggest that the finest period is the four weeks surrounding 01 September. Presently, auroral displays and also natural-radio phenomena are at a minimum due to overall minimal solar-activity as we approach deep Solar-Minimum, although some report signs of the coming Cycle 25 with new Sunspots occurring at high solar latitude already). Aurora appears most frequently and brightly during the equinoctal periods around September and April (due to the alignment of Earth's magnetic-field and the IPF). Periods of fast solar-wind streams (>500 to 600 km/sec speeds) will often produce nice aurora and potentially a magnetic storm, too.
