All-Sky Aurora #3 — November 4, 2021

A sky-filling Kp7-level aurora on the morning of November 4, 2021, from home in southern Alberta. The aurora was pulsing and flaming upwards over most of the sky, while more normal curtains slowly moved across the north. For a few minutes, very prominent red-topped curtains formed and filled the northern sky and moved from west to east. This was just past their peak. Note the blue curtains to the east as they catch the sunlight at their high altitude pre-dawn. A little pink nitrogen fringe appears along the bottom of the bright curtains low in the north. This is a single 6s shot with the 7.5mm TTArtisan fish-eye lens at f/2 and the Canon R6 at ISO 3200. Taken at 5:06 am MDT.

Panorama of the Auroral Storm of October 11, 2021

A 120° panorama of the initial arc of Northern Lights at the start of an evening of aurora during a G2 storm on October 11/12, 2021, Thanksgiving Day in Canada. This was from home in southern Alberta, Canada. Moonlight from the waxing crescent Moon tints the sky. Note the subtle shades of red and variations of green in the arc. The panorama shows off the classic auroral oval centred on the direction of the north magnetic pole, to the northeast of true north at my longitude in western Canada. The Big Dipper is at left and its Pointer stars in the bowl point up to true north (Polaris is off the frame). This is a panorama of 13 segments at 15° spacings, with the RF 28-70mm lens at 28mm and at f/2 on the Canon R6 at ISO 1600 for 4 seconds each. Stitched with Adobe Camera Raw.

Red Aurora from Dinosaur Park (August 29, 2021)

A dim red and green aurora from Dinosaur Provincial Park, Alberta, on August 29/30, 2021. There were expectations of a bigger display this night, but litte came to pass! Capella is rising at centre; Perseus is at top right. This is a stack of 4 exposures for the ground to smooth noise and one exposure for the sky, all 30 seconds at f/2.8 with the Canon 15-35mm RF lens at 25mm and the Canon R6 at ISO 4000.

Aurora from Home (August 24, 2021)

A mild display of Northern Lights in the moonlight, from home in southern Alberta, August 24, 2021. This is a single 15-second exposure with the 15-35mm RF lens at f/2.8 and 20mm, on the Canon R6 at ISO 800.

Perseid Meteor Shower over Dinosaur Park

A composite showing about three dozen Perseid meteors accumulated over 3 hours of time, compressed into one image showing the radiant point of the meteor shower in Perseus. This was August 12, 2021, from The Trail of the Fossil Hunters trailhead lot in Dinosaur Provincial Park, Alberta. A dim magenta aurora is visible to the northeast at left. Cassiopeia is at centre above the radiant point; the Andromeda Galaxy is just right of centre. Capella is rising at left. Airglow also tints the sky. This is a blend of: a single 30-second exposure for the background sky, one with the aurora at its most active, such as it was this night, with a stack of 8 x 30-second exposures for the ground to smooth noise. Then 32 x 30-second exposures for the individual meteors (a couple of frames have two meteors on them) are overlaid with Lighten blend mode onto the base sky image, each with masks to reveal just the meteors. All frames were with the Canon R6 at ISO 6400 and with the TTArtisan 11mm fish-eye lens at f/2.8. The camera was on a static tripod, not tracking the sky, so I hand-rotated all the meteor frames around Polaris at upper left, to bring them into close alignment to the base sky image, so the positions of all the meteors are close to their actual positions in the starfield when they appeared. A couple of exceptions were the meteors at bottom which appeared in Taurus, below the horizon at the time the sky image was taken, so those meteors are moved up artificially. ON1 NoNoise applied to the sky image. Ground illumination is from starlight.

Aurora and Distant NLCs (June 11-12, 2021)

A display of Northern Lights low across the northeast, with a very distant and low showing of noctilucent clouds (NLCs) to the north along the northern horizon at left. These would have been far to the north of me. This was about 1 am MDT. This is a single 30-second shot with the 21mm TTArtisan lens at f/2.8 and Canon R6 at ISO 1600. Taken from the field at home.

Aurora from Home on June 10, 2021

A mild aurora with the glow of perpetual solstice twilight across the north, on the night of June 10/11, 2021. Taken with the TTArtisan 21mm lens as part of testing.

SAR Arc of Red Aurora (May 11-12, 2021)

An auroral arc at left across the northern horizon with a faint red SAR — Stable Auroral Red — arc to the east. The SAR arc was not visible to the eye. The camera was the red-sensitive Canon EOS Ra so that helped pick up the dim deep red glow. The wide lens captures the broad sweep of the summer Milky Way rising, arcing from NE at left to SE at right, with the galactic core area at far right. This is a single tracked exposure for 2 minutes at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens, on the EOS Ra at ISO 1600, and on the MSM tracker.

Arc of Green and Red Aurora (May 11-12, 2021)

A green auroral arc across the northern horizon with faint red components above, with a touch of blue as well. The red glow forms a very dim red arc high across the north which is likely a SAR — Stable Auroral Red — arc. It became more prominent a few minutes later when the main arc died down in intensity. The camera was the red-sensitive Canon EOS Ra so that helped pick up the dim deep red glow. The wide lens captures the full sweep of the auroral arc from NW at left to NE at right. This is a single untracked exposure for 30 seconds at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens, on the EOS Ra at ISO 3200.
