Details:
A bit of a surprise aurora on April 19! The Bz turned way south and the sky really lit up in the late evening as a storm hit. The aurora was going as the sky darkened and began to cover the sky by 11:30 MDT.

The main image is a 220° panorama from west (left) to east (right) of the bright aurora in a classic arc across the north, on April 19, 2019. This was from a roadside pullout on Highway 564 north of Strathmore, Alberta.

The waxing crescent Moon is setting at left in the northwest; Jupiter is rising at far right in the southeast. The lights of Calgary light the sky and clouds at far left.

This is a 10-section panorama stitched with Camera Raw. All 8-second exposures at f/2.8 with the Sigma 24mm Art lens and Nikon D750 at ISO 1600.

The second image is a smaller panorama of the bright aurora of April 19, 2018 over a frozen pond and farm on Highway 564 at Highway 24, northeast of Strathmore, Alberta.

This is a 4-section panorama stitched with Camera Raw. All 5-second exposures at f/2.8 with the Sigma 24mm Art lens and Nikon D750 at ISO 800.
