India’s first solar observatory, Aditya-L1, has played a crucial role in helping scientists understand the unusual behaviour of the strongest solar storm in over two decades, which struck Earth in May 2024, according to the Indian Space Research Organisation (ISRO).

What is a Solar Storm?

A solar storm is a sudden release of energy, charged particles, magnetic fields, and solar material from the Sun into the solar system. These events are driven by intense solar activity and are a key component of space weather phenomena.

Causes of Solar Storms

The Sun has a complex and tangled magnetic field. Due to the Sun’s differential rotation—where the equator rotates faster than the poles—these magnetic field lines become twisted and stressed.

When the stress becomes excessive, the magnetic field lines snap and reconnect, a process known as magnetic reconnection, releasing enormous amounts of energy and triggering solar storms.

Major Components of a Solar Storm

1. Solar Flares

A solar flare is an intense burst of radiation from the Sun.
It emits energy across the entire electromagnetic spectrum, including X-rays, gamma rays, ultraviolet rays, radio waves, and visible light.

Solar flares are the most powerful explosions in the solar system, with the largest equivalent to billions of hydrogen bombs.

2. Radiation Storms

Solar eruptions can accelerate charged particles such as protons and electrons to extremely high speeds, resulting in radiation storms.
The fastest particles can reach Earth from the Sun—about 93 million miles away—in less than 30 minutes.

3. Coronal Mass Ejections (CMEs)

A Coronal Mass Ejection (CME) is a massive cloud of electrically charged plasma ejected from the Sun’s outer atmosphere, known as the corona.
A single CME can release billions of tonnes of solar material into space and often appears like a giant bubble bursting from the Sun.

Effects of Solar Storms on Earth

When solar storms are directed towards Earth, they can cause geomagnetic storms by disturbing Earth’s magnetic field.
These disturbances can lead to:

• Radio communication blackouts

• Satellite navigation and communication disruptions

• Power grid failures

• Spectacular auroras in polar regions

However, solar storms do not directly harm humans, as Earth’s magnetic field and atmosphere provide effective protection.

The International Criminal Police Organization (INTERPOL) has recently issued a Blue Corner Notice against the missing owners of a nightclub in Goa following a deadly fire incident. The notice was issued to assist Indian investigating agencies in locating the individuals and verifying their identities through international cooperation.

Meaning of a Blue Corner Notice

A Blue Corner Notice, also referred to as an Enquiry Notice, is an international alert issued by INTERPOL to collect information about a person involved in a criminal investigation. It allows law enforcement agencies of member countries to share and seek details regarding the identity, location, and activities of a person of interest.Importantly, a Blue Corner Notice is issued before the filing of formal criminal charges and does not carry any authority for arrest or detention.

Purpose and Use

The primary purpose of a Blue Corner Notice is to support ongoing investigations by enabling international information exchange. It is used to determine the whereabouts of a person, verify identity details, and gather background information such as criminal records or travel history.It functions as an investigative and intelligence-gathering mechanism, particularly useful in cases involving cross-border movement.

Key Characteristics

A Blue Corner Notice is part of INTERPOL’s colour-coded notice system and is circulated among all 196 member countries. It is non-coercive in nature and relies on voluntary cooperation from national law enforcement agencies. The notice is meant strictly for information-sharing and not for law enforcement action such as arrest.

Difference Between Blue Notice and Red Notice

A Blue Corner Notice is issued to collect information and trace a person’s location, whereas a Red Notice is issued to locate and provisionally arrest a person wanted for prosecution or to serve a sentence. Unlike a Red Notice, a Blue Notice has no enforcement implications.

Other INTERPOL Notices

INTERPOL also issues other notices such as Yellow Notices for missing persons, Black Notices for unidentified bodies, Green Notices to warn about dangerous individuals, Orange Notices for public safety threats, Purple Notices for sharing criminal techniques, and Silver Notices to trace criminal assets.

About INTERPOL

The International Criminal Police Organization (INTERPOL) is an independent international body that facilitates cooperation among national police forces to combat transnational crimes. It has 196 member countries, with India joining in 1949. INTERPOL is not a part of the United Nations, though it has enjoyed Permanent Observer status at the UN since 1996. Its headquarters are located in Lyon, France.

Conclusion

The Blue Corner Notice is a crucial tool for enhancing international police cooperation by enabling timely exchange of information during investigations. It helps countries track individuals across borders while respecting national sovereignty and legal frameworks
