January 17: Solar wind is fast, expect decent northern lights tonight. Check real time data regularly and watch for the aurora on-switch, Bz south under Bz value. Not much will be seen if Bz is north. Venus brilliant in southwest after sunset next to Saturn.
When the Bz value points south, aurora is active. Faster solar wind expands the auroral oval. Higher density leads to more colourful displays.
Record of measurements at Leirvogur for the past 6 hours.
