This is a 270° panorama of the auroral arc seen across the northern sky on January 14, 2023. It is framed between the setting summer Milky Way (at left in the northwest) and the rising winter Milky Way (at right in the southeast). To the west (right) of the winter Milky Way is Orion, with Sirius below, while above is Aldebaran, the Hyades, reddish Mars, and the blue Pleiades at upper right. The Big Dipper and Ursa Major are above the main arc of aurora to the north at centre. Polaris is at top, left of centre. Cygnus (with the star Deneb) and Lyra (with the star Vega) are setting at left above my house. The auroral arc shows the characteristic yellow-green colour but also upper altitude reds, both from oxygen atoms. The Kp index was about 4 this night, though peaking to Kp5 at times. Clouds rolling in later prevented me from catching more of the show later when it apparently got more active. Taken from home in southern Alberta (latitude 51° N) on January 14, 2023, in a 7-section panorama, each section with the Venus Optics 15mm lens at f/2 on the AstroGear filter-modified Canon R at ISO 800, for 20 seconds each. Stitched with Adobe Camera Raw. I was testing the Canon R camera this night.
