Mesmerising halo forms around Sun over Karachi: Here’s why

Published

Karachiites witnessed a sun halo on Tuesday reflecting changes in weather.

The meteorological expert revealed that a sun halo — also known as a 22-degree halo — occurs due to sunlight refracting in millions of hexagonal ice crystals suspended in the atmosphere.

According to The Times of India, circular halos specifically are produced by cirrus clouds, which are thin, detached, hair-like clouds.

It should be noted that these clouds are very high up in the atmosphere, at a height of over 2,000 feet.

What causes sun halo to appear?

According to the UK-based Atmospheric Optics, a knowledge-sharing website, the halo phenomenon happens when the light is reflected and refracted by ice crystals and may split into colours because of dispersion.

Reports suggest that usually, halo indicates that rain will fall within the next 24 hours since the cirrostratus clouds that cause them can signify an approaching frontal system.

Earlier this month, the world witnessed the first solar eclipse of the year 2023.

Eclipses occur when the moon sun and earth align in a rare cosmic setting casting their shadow or blocking the sunlight. 

April has been designated as “Global Astronomy Month” by a US-based organisation Astronomers Without Borders, as the month will offer mesmerising sights in the sky, as per the report by Popular Science.

The April 20 solar eclipse created a ring of fire which was witnessed for a brief time in the Indian Ocean but the moon covered the sun completely when it reaches Western Australia witnessing around nine minutes of darkness during the day.

Sources claim that Babar was reappointed as the cricket team’s captain.

Reappointing Babar Azam to lead the national squad upon the call of the newly-formed selection committee was decided by the Pakistan Cricket Board (PCB) on Friday.

Sources claim that Babar will captain the Green Shirts in the upcoming five-match Twenty20 series against New Zealand, which kicks off on April 20.

After the team’s crushing defeat in the ICC World Cup 2023, Shaheen Shah Afridi was chosen as the white-ball captain, while Shan Masood was named the red-ball captain by the previous PCB administration.

The sources claimed that Babar’s appointment as captain was suggested by the selection committee. They said he will go to the Kakul training camp as captain.

Shaheen had chosen to step down, but his close friends urged him against it and to wait for the PCB’s decision, according to individuals close to him.

After guiding the team for four years, Babar resigned as captain of the national team in all formats in November of last year. After Pakistan’s poor performance in both the Asia Cup and the World Cup, where they were unable to advance to the semi-finals, he faced criticism for several months.

Although Babar was named Test and white-ball captain in 2020 and 2019, respectively, the side has neither won an Asia Cup nor an ICC championship while he has been captain.
