Consider the following statements with reference to the Double Sun hal...
Explanation:
- Double Sun halo:
The Double Sun halo is an optical phenomenon where two concentric rings appear around the sun.
- Occurrence:
This phenomenon occurs when sunlight is refracted through ice crystals suspended in cirrostratus clouds, not cumulonimbus clouds as mentioned in statement 2.
- Explanation of the phenomenon:
When sunlight passes through these ice crystals, it gets refracted or bent, resulting in the formation of the two concentric rings around the sun. The inner ring is typically red in color and the outer ring is blue or purple.
- Appearance:
The Double Sun halo is a rare and beautiful sight in the sky, often associated with changes in weather conditions.
- Significance:
This optical phenomenon is not only a visually stunning sight but also serves as a reminder of the intricate interactions between sunlight, ice crystals, and atmospheric conditions.

Consider the following statements with reference to the Double Sun hal...
Recently, a rare celestial phenomenon known as a "double sun halo" was witnessed in the skies over Ladakh.
- It is a rare optical phenomenon where two concentric rings appear around the sun.
- This occurs when sunlight is refracted through ice crystals suspended in cirrus clouds, creating this dazzling visual effect.
- It is a variation of the more common 22-degree halo, where a bright ring encircles the sun.
- In this case, two halos are visible - an inner halo with a radius of approximately 22 degrees and an outer halo with a radius of around 46 degrees from the sun's center.
- Formation:
- The formation of a double sun halo is a result of the unique shape and orientation of the ice crystals in the cirrus clouds. These crystals, typically hexagonal in shape, act as natural prisms, refracting and reflecting the sunlight in specific angles.
- When the ice crystals are randomly oriented, the refracted sunlight creates the inner 22-degree halo. However, if the crystals are aligned horizontally, with their flat faces parallel to the ground, an additional refraction occurs, resulting in the outer 46-degree halo.
- This precise alignment of the ice crystals is rare, making the double sun halo a relatively uncommon sight, especially in regions like Ladakh, where the atmospheric conditions are ideal for such phenomena.
Hence only statement 1 is correct.
