Lunar Upper Tangent Arc and Aurora Borealis. November 19, 2024.

As the bright moon was about to rise, I noticed an Upper tangent arc above the mountainside. A brief, and mild display of the northern lights occured, and colored the wintry scene. A few images of the display displayed below. Photo details: Canon 650D, Samyang 8mm fisheye-lens.

Comet C/2023 A3 Tsuchinshan-ATLAS.

A brief, in-between clouds and tree branches, exposure of fading Comet C/2023 A3 Tsuchinshan-ATLAS on October 28, 2024. Details: Sigma 50-500mm lens, Canon 800D

OCTOBER 19, 2024.

More cloudy this evening, but got a chance to observe/photograph the comet in-between clouds. Still an interfering Moon. Photo details: Canon 800D, Sigma 50-500 mm lens

OCTOBER 18, 2024.

The weather finally collaborated. Albeit, the moon strongly influenced the conditions, it was nice to get a view of the comet. Or, rather a few photos of the comet. A couple enclosed. It was not possible to see the comet without optical aids. Photo details: Canon 800D, Sigma 50-500 mm lens

Aurora borealis, and an east-west oriented arc. September 13/14, 2024.

It finally cleared up (somewhat), but not so good conditions. It was indeed a colorful display, in between clouds, and beyond fog. However, the most interesting feature was an east-west oriented arc. It formed at about UTC 21.25 and lasted until about UTC 21.36 it was followed by an intense aurora. The arc appeared in the same loacation where I previously most often have seen/observed STEVE. Please, find timestamp on images. Photo details: Canon 650D, Samyang 8 mm fisheye-lens

STEVE, and Aurora Borealis. April 21, 2024.

There was a brief instance of auroral activity on April 21. Not easily seen or photographed because of a bright sky. Interestingly, the contrail like phenomenon STEVE was observed from about UTC 21.02 to 21.34.

STEVE over the mountain. The faint mauve color was captured by an allsky camera (AMS135). Taken at the same time as the DSLR photos below.
