SEPT 13 AURORA PANORAMA Taken by Alan Dyer on January 13, 2018 @ near Gleichen, Alberta



Panorama of the Northern Lights and Winter Stars

Heres a 240° panorama of the Northern Lights on September 13, in a minor display that night. While it never got very active, despite a Kp of 5, this was the first display weve seen from around Alberta in some time, between the poor winter weather and inactive Sun.

The aurora is to the north (left of centre), then the panorama sweeps around to the south (at right) to include the winter stars of Orion and Canis Major. Sirius is in some cloud, accentuating its size and colour. Leo is rising at centre.

The Big Dipper and Ursa Major are left of centre.

The Milky Way appears at far left, in the area of Perseus and Cepheus, and again at far right through Monoceros and past Orion and Canis Major.

The aurora displays the characteristic green and red curtains from oxygen, but there is also a dim red curtain at left (northwest) and at centre (east) south of the main curtain and separated. It looks like a dim Steve arc but this was not visible to the eye and never became well formed or bright.

This is a stitch of 8 segments with the 14mm Sigma Art lens, at f/2 for 13 seconds each, and Nikon D750 at ISO 3200. Stitched with Adobe Camera Raw. I shot it about 11 pm MST.
