A view looking straight up to the zenith with the isolated auroral arc known as STEVE arcing across the sky, with his characteristic pink color and showing some fingers of green in his usual picket fence appearance. This was about 1:40 am MDT time on April 10 at home in southern Alberta. The Big Dipper is above centre; Arcturus is below and left. Leo and Regulus are at lower right. The naked eye Coma Berenices cluster is below centre. This was with the Canon 6D MkII and Rokinon 14mm SP.
Auroral curtains in twilight on March 14, 2018 from at sea north of Tromsø, Norway, on the Hurtigruten ship the m/s Nordnorge, with the curtains showing a purple tinge to the background sky, likely from scattered blue sunlight mixing with the red oxygen colours. The Big Dipper is at upper left; Orion is at far right; Leo is left of centre, in a view looking south. This is a single 2-second exposure with the Rokinon 12mm full-frame fish-eye at f/2.8 and Nikon D750 at ISO 8000.
