EU Halo Saturday: A Spectacular Atmospheric Optics Event

On February 27th, a remarkable atmospheric optics phenomenon occurred over the European Union, captivating skywatchers from Hungary and Slovakia to Paris in the west. This event, known as "EU Halo Saturday," showcased a stunning display of halos, arcs, and sundogs, creating a visual spectacle in the sky.

Searching for Halos: Techniques and Tips

Photographer Monika Landy-Gyebnar from Hungary captured some breathtaking shots that demonstrated effective ways to search for halos amidst the glare of the sun. By utilizing reflections from convex surfaces, particularly those made of dark glass, Landy-Gyebnar was able to capture halos in all their splendor. She found that sunglasses lenses, car windows, and even reflections in pools of water proved to be helpful tools in spotting these atmospheric phenomena.

Unveiling the Atmospheric Marvels

Landy-Gyebnar's photographs unveiled a variety of captivating atmospheric optics features. Shielding the sun with a bus shelter, she revealed a bright upper tangent arc above a weaker 22-degree halo. Additionally, another image taken by David Berecz in Kolárovo, Slovakia showcased an unusually bright lower tangent arc. These unique phenomena added to the intrigue and wonder of EU Halo Saturday.

Awe-Inspiring Halos over Hungary and Slovakia

Landy-Gyebnar's photographs from Hungary displayed halos over Lake Balaton, taken by Tamas Ladanyi. The images showcased a massive circumscribed arc and hints of a parhelic circle. These grand celestial formations further highlighted the ethereal beauty of the event.

Prismatic Sundogs near Paris

Denis Joye's photograph taken near Paris captured a perfect 22-degree halo flanked by two prismatic sundogs. Sundogs are vibrant patches of light that appear on either side of the sun, caused by the refraction of sunlight through ice crystals in the atmosphere. Joye's image showcased the symmetrical and striking nature of these sundogs, complementing the overall spectacle of EU Halo Saturday.
