Boiling Sunspots: Unveiling the Distorted Sunrise in Hungary

Have you ever witnessed a sunrise that seemed to defy the laws of nature? Monika Landy-Gyebnar, an avid sky watcher from Hungary, captured an extraordinary event on November 2nd, 2015. The sun's rays passing through multiple temperature inversion layers created a mesmerizing spectacle as they split and distorted its image. This phenomenon, known as boiling sunspots, occurs when the inversions are particularly strong. In some cases, it can even cause the sun to rise unexpectedly early, a phenomenon called the Novaya Zemlya effect.

As the sun climbs higher in the sky, its light interacts with the layers of temperature inversions, resulting in a unique visual display. The effect is relatively weak under normal conditions, but when the inversions are stronger, a mock-mirage can be observed. These mirages create optical illusions, bending and distorting the appearance of the sun. However, despite the atmospheric distortion, a massive sunspot group managed to survive and shine through the chaos.

The sunspot group captured in Landy-Gyebnar's images stretched an astonishing 12 Earth diameters across the solar disk. This impressive size is a testament to the intensity and scale of these solar phenomena. As the sun climbed through the layered air, the sunspot group appeared to alter from second to second, showcasing the dynamic nature of these celestial features.

To further appreciate the intricacies of this sunspot group, let's take a closer look at Les Cowley's eyepiece sketch. Using a 60mm H-alpha scope at 80X magnification, Cowley observed the sunspots a day earlier. In the near monochromatic light of excited hydrogen atoms, he meticulously documented their appearance. Interestingly, the slight tilt observed in his sketch is solely due to Earth's rotation.

It is important to note that observing the sun directly can be extremely dangerous and should never be attempted without proper equipment. Looking at the sun through optical devices such as cameras or telescopes not designed for safe solar viewing can result in severe eye damage or even blindness. Always prioritize your safety and consult professionals or use equipment specifically designed for solar observation.

In conclusion, the boiling sunspots phenomenon witnessed by Monika Landy-Gyebnar in Hungary on November 2nd, 2015, showcases the incredible interplay between the sun's rays and temperature inversion layers in our atmosphere. This mesmerizing event not only distorts the sunrise but also provides a glimpse into the immense scale of sunspot groups. Remember to exercise caution when observing the sun and seek professional guidance to ensure a safe and awe-inspiring experience.

Boiling Sunspots

Monika Landy-Gyebnar imaged this sunrise from Hungary on 2nd Nov �15.

As the sun climbs its rays pass through multiple temperature inversion layers that split and distort its image. The effect is relatively weak. When the inversions are stronger a mock-mirage is seen. When very strong indeed the sun might rise unexpectedly early � a Novaya Zemlya effect.

At lower middle a huge sunspot group stretching 12 Earth diameters across the disk has survived (just!) the atmospheric distortion.

A few video frames. The sunspot group appears to alter from second to second as the sun climbs through the temperature layered air.

Eyepiece sketch by Les Cowley - 60mm H-alpha scope 80X. The different tilt is purely the effect of Earth's rotation.

Never look at the sun through any optical equipment - cameras or telescopes - unless it is professionally designed for safe solar viewing.
