Seems to be some higher Geomagnetic activity happening again today.

^^ Good page trying to forecast the likelihood of northern lights in southern Alberta.
Seems like when it gets to level 6 or 7 on clear nights we have a good chance of seeing northern lights in Calgary.
Hopefully there will be more chances to see them in Calgary over the next year or so with the solar sunspots approaching the peak of their 11 year cycle.
