The Northern Lights dance over the prairie landscape of Grasslands National Park.
The aurora warnings were out for last night but I hadn’t expected to see much. But about 10:30 pm a faint arc appeared to the northeast. The display brightened about local midnight (Central Standard Time here in Saskatchewan) and became fairly active for a time.
The main arc increased in intensity and moved with fine structure and detail. The eye could see some faint, colourless curtains extending upward but the camera picks them up as red, typical of auroral curtains reaching into the top of the atmosphere.
I shot these from the Frenchman River valley, a wide coulee formed by glacial rivers and now the heart of the West Block of Grasslands National Park.
It was a beautifully dark site except for flashes of spotlights now and then (not seen in the photos here) from naturalists doing census studies of the nocturnal and endangered black-footed ferret recently re-introduced to the Park. Ironically, their lights spoiled the otherwise pristine and pitch-black night in this dark sky preserve.

The Amazing Sky 
Gorgeous colors, Alan. Was this shot with your filter-modified 6D, and does that intensify the reds?
Hi Ralph, no the 6D is stock but still picks up the reds very well. But a modified camera would do even better.
Alan, those are absolutely breathtaking
