ISRO's Aditya L1 captures first high energy X-ray glimpse of solar flares
Bengaluru, Nov 7: ISRO's maiden solar mission, Aditya L1, has captured its first high energy X-ray glimpse of solar flares.
During its first observation period from approximately October 29, the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) on board Aditya-L1 spacecraft has recorded the impulsive phase of solar flares, the space agency said in a statement on Tuesday.
A solar flare is a sudden brightening of solar atmosphere.
The recorded data is consistent with the X-ray light curves provided by National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellites (GOES).
"Commissioned on October 27, 2023, HEL1OS is currently undergoing fine-tuning of thresholds and calibration operations. The instrument is set to monitor the Sun's high-energy X-ray activity with fast timing and high-resolution spectra," it said.
HEL1OS data enables researchers to study explosive energy release and electron acceleration during impulsive phases of solar flares.
HEL1OS was developed by the Space Astronomy Group of the U R Rao Satellite Centre, ISRO, Bengaluru, the agency added.
HEL1OS, the hard X-ray spectrometer on Aditya-L1 Solar Mission by ISRO, is the harbinger of flaring activities on the Sun, with the ability to capture the early impulsive phase of the solar activity.
According to ISRO, flares produce enhanced emission in all wavelengths across the electromagnetic spectrum radio, optical, UV, soft X-rays, hard X-rays and gamma-rays. Flare emission consists of emissions from accelerated particles and hot plasma.
Aditya-L1 spacecraft is designed for providing remote observations of the solar corona and in-situ observations of the solar wind at L1 (Sun-Earth Lagrangian point), which is about 1.5 million kilometres from the Earth.
It is the first dedicated Indian space mission for observations of the Sun. Aimed at studying the Sun from an orbit around the L1, the mission carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun, the corona, in different wavebands.
Aditya-L1 is a fully indigenous effort with the participation of national institutions.
An ISRO scientist told PTI that capturing the first High-Energy X-ray glimpse of Solar Flares is an indication that the mission is so far doing well on the expected lines.

Not UN’s role to regulate AI, says Guterres as world body plans annual global dialogue
United Nations (PTI): It is not the UN’s role to regulate AI, Secretary General Antonio Guterres has emphasised as he pointed to an annual global dialogue being planned at the international organisation on AI with participation from all countries, governments, private sector as well as civil society.
Guterres will soon be arriving in New Delhi to attend the India AI Impact Summit, the first-ever summit on Artificial Intelligence hosted in the Global South.
In an exclusive interview to PTI ahead of his visit to India for the Summit, Guterres outlined efforts by the international organisation aimed at global cooperation on Artificial Intelligence (AI), emphasising that these are “perfectly in line” with the strategy demonstrated by India in its leadership of the AI summit.
Guterres highlighted three key areas under the Global Digital Compact initiated at the UN to contribute towards the global AI architecture.

The first is the creation of a new high-level Independent International Scientific Panel on Artificial Intelligence comprising 40 experts from around the world.
The UN General Assembly last week appointed the 40 members recommended by Guterres to the independent panel.
Head of the Department of Data Science and Artificial Intelligence (DSAI) at IIT Madras Balaraman Ravindran is among the global group of 40 distinguished experts recommended by Guterres to serve on the panel for a three-year term from date of appointment.
Guterres said that through the panel, “We will have a totally independent and universal…scientific body (that will be) able to tell the world at each moment where are we in relation to AI? What are the advances that were made? What are the discoveries that were established? What are the risks of (various) mechanisms or instruments, and to do it in a totally independent way.”
He described this as a “fantastic source” of information for governments to take the right decisions in policies and measures in relation to AI and “for the people at large to know public opinions, in democratic countries like India that is very important.”
Guterres also pointed to an annual global dialogue being planned at the UN on AI with participation from all countries, governments, private sector as well as civil society.
Emphasising that it is not the UN’s role to regulate AI, Guterres said the global dialogue will be a “platform where everybody can come and everybody can discuss, and where we can learn with each other and eventually come to some possible consensus on the best way to maximise the opportunities of AI and minimise its risks.”
Lastly, he expressed hope that his proposal of a fund will be approved.
“There was an agreement in the General Assembly in order to support developing countries to build capacity to be able to benefit from AI. So these are three very important contributions of the UN and I believe that these contributions are perfectly in line with the strategy that India has demonstrated in the leadership in the preparation of the present Summit,” he said.
The UN chief has proposed a voluntary global fund of up to three billion dollars to support countries in the field of AI capacity building.
The Global Digital Compact, adopted at the 2024 Summit of the Future, had set out a shared vision for an open, safe and inclusive digital future.
Among its commitments was the creation of an Independent International Scientific Panel on AI to advance scientific understanding and ensure that international deliberations are informed by the best available evidence, the UN has said.
Stéphane Dujarric, Spokesperson for the Secretary-General, told reporters that Guterres is scheduled to participate in the Summit’s opening ceremony, a plenary with heads of state and government, as well as a session on the role of science in international AI governance.
The Secretary-General will have bilateral meetings with President Droupadi Murmu, Prime Minister Narendra Modi and will also meet with other global and tech leaders attending the Summit, as well as members of the International Scientific Panel on Artificial Intelligence.
While in India, Guterres is also scheduled to take part in a roundtable organised by the UN to discuss renewable energy and energy transition.
"With India emerging as a global leader in renewable energy expansion, the discussion will bring together senior figures from industry, finance, policy and civil society to identify concrete steps to further accelerate renewable energy deployment, strengthen grids and storage, and mobilise investment at scale.
“This engagement is part of the Secretary-General’s continued efforts to advance a faster, fairer and more inclusive global energy transition, aligned with the Paris Agreement,” Dujarric said.
United Nations India said in a statement that over 30 events organised by the UN system are scheduled during the five-day summit, and will include sessions on AI for resilient agriculture, health systems innovation, ethical AI governance, women’s leadership in technology, digital capacity-building in the Global South and responsible business practices.
The statement by the UN in India said that discussions will focus on “how AI can accelerate progress towards the Sustainable Development Goals while safeguarding human rights and addressing emerging risks”.
At the Summit, Guterres will be joined by senior UN leaders, including UN High Commissioner for Human Rights Volker Türk; Under-Secretary-General and UN Secretary-General’s Envoy on Technology Amandeep Singh Gill and Special Representative of the Secretary-General for Disaster Risk Reduction Kamal Kishore.
Also participating are Managing Director of the International Monetary Fund Kristalina Georgieva; Director-General of the International Labour Organisation Gilbert Houngbo and Secretary-General of the International Telecommunication Union Doreen Bogdan-Martin.
