Northern Lights

We were just outside Banff, AB, when my phone app told me that we had a KP index of 9.  I'd never seen that before.  A couple of hours later, based on a local's suggestion, we were inside Banff National Park, along a small lake with mountains, amongst hundreds of friends that we'd never met.  We had a front row view of what some people are describing as the best viewing of the Lady Arora our southern Canadian generation has ever seen.
