When the Sun Bounces
الشرح: First place winner in the 2023 IAU OAE Astrophotography Contest, category of Still images of sunrise and sunset location over the year.
This image was taken at Norway's North Cape. Owing to the latitude of this location, the Sun never truly sets during the summer months, from around April to August. This results in the unique spectacle of continuous daylight, known as a polar day. This captivating series of images, taken in 2022, showcases the Sun's relentless journey across the horizon every 30 minutes. At its lowest point in the sky, the Sun does not set, but appears to bounce off the horizon. The globe on the far right in the photo stands as a sentinel, marking the northernmost point of the European continental mainland.

The Eclipse Clock-Eclipse on a Polar Day
الشرح: First place winner in the 2023 IAU OAE Astrophotography Contest, category of Still images of day arcs of the Sun and Solargraphs.
Constructed by combining multiple images over the course of a 24-hour period, the image was captured in Union Glacier, Antarctica, during the total solar eclipse of 4 December 2021, and showcases the day arc of the Sun. It illustrates the unique phenomenon of a polar day, during which the Sun travels around the sky without setting. During polar days, areas within the polar circles experience 24 hours of continuous daylight, and the Sun doesn’t set for an extended period. The image also offers a rare perspective of a solar eclipse, where the Moon passes between the Sun and Earth, and as viewed from Earth. This can be seen in the lower image of the Sun, where the Moon covers the solar disc.
