The Reason the Year 2026 Is Set to Be a Year Like No Other for India's Solar Observation Mission

Regarding Aditya-L1, 2026 will be truly unique.

This marks the initial occasion the observatory – which was placed in orbit recently – will be able to observe our star when it reaches its maximum activity cycle.

According to research, this occurs roughly once every 11 years as the Sun's magnetic poles flip – a similar Earth scenario would be the planet's poles changing places.

It's a time marked by intense activity. It sees the Sun transition from peaceful to violent and is marked by a significant rise in the frequency of solar eruptions and massive solar flares – massive bubbles of plasma that erupt from the solar corona.

Made up of ionized particles, a CME may have a mass up to a trillion kilograms and can attain velocities exceeding 2,000 miles each second. It can head out in any direction, even toward the Earth. At maximum velocity, it would take an ejection about half a day to cover the vast distance between Earth and the Sun.

"During typical or low-activity times, the Sun launches two to three CMEs a day," explains an astrophysics expert. "In 2026, it's anticipated them to be over ten daily."

Researching coronal mass ejections is one of the key research goals of India's maiden solar mission. Firstly, as these eruptions provide an opportunity to study the star at the centre of our planetary system, and two, since events that take place on the solar surface endanger infrastructure on Earth and in orbit.

Effects on Our Planet and Orbital Systems

CMEs seldom present immediate danger to people, but they do affect life on Earth by causing magnetic disturbances affecting the weather in Earth's vicinity, where nearly 11,000 satellites, including Indian satellites, are stationed.

"The most spectacular manifestations from solar eruptions include northern lights, being direct evidence that solar particles from Sun journey to Earth," the scientist explains.

"But they can also cause electronic systems on a satellite malfunction, disable electrical networks and disrupt weather and communication satellites."

Historical Solar Incidents

• The most powerful solar storm in history occurred during the 1859 solar superstorm which knocked out telegraph lines across the globe
• During 1989, sections of Quebec's power grid failed, leaving millions without power for nine hours
• During late 2015, solar activity disturbed flight operations, causing disruption across Scandinavia and some other European air hubs
• In February 2022, an ejection had led to 38 commercial satellites being lost

With capability to observe what happens in the solar atmosphere and spot solar activity or a coronal mass ejection in real time, measure its heat at the source and track its trajectory, it can work as a forewarning to switch off power grids and spacecraft and move them to safety.

The Mission's Special Capability

There are other space observatories watching the Sun, India's spacecraft holds an edge compared to rivals when it comes to watching the corona.

"The instrument has perfect dimensions that lets it effectively simulate lunar coverage, completely blocking the solar disk and allowing it continuous observation of almost all solar atmosphere around the clock, throughout the year, including during eclipses and occultations," says the researcher.

In other words, this instrument acts like a synthetic eclipse, obscuring the solar glare allowing researchers continuously observe its faint outer corona – something natural eclipses provide only during specific moments.

Moreover, this is the only mission that can study solar events using optical wavelengths, enabling it to determine eruption heat and thermal output – key clues that show how strong of an eruption when traveling toward Earth.

Preparation for Peak Period

To prepare for next year's solar maximum, scientists worked together to study the data obtained from one of the largest CMEs recorded by the mission has recorded until now.

This event began in September 2024 during early hours. The eruption's weight was 270 million tonnes – the iceberg that sank Titanic weighed much less.

At origin, the heat reached extreme levels and the energy content comparable to 2.2 million megatons of TNT – relative to nuclear weapons used in Japan were much smaller in scale each.

Although the numbers seem massive, the expert describes it as a "medium-sized" one.

The asteroid that eliminated the dinosaurs on our planet carried enormous energy and when solar peak occurs, we could see eruptions with energy content equal to even more than that.

"In my view this eruption we analyzed to have occurred during periods was in the normal activity phase. Now this sets the standard that we'll be using to evaluate what to expect when the maximum activity cycle occurs," he states.

"The insights from this will help us developing protective measures to be adopted safeguarding satellites in near space. They will also help us gain a better understanding of our space environment," he adds.
