The sun fired off a powerful flare at 09:07 Beijing Time on Friday, which was captured in great clarity by China's Fengyun-4C geostationary meteorological satellite, according to the China Meteorological Administration.
The flare was observed from the active region 14419 near the sun's northwest limb and peaked at X2.4. Flares are classified from C, the weakest, to M, of moderate strength, and X, the strongest.
The blast caused temporary disruptions to shortwave radio communications and satellite navigation signals.
It was accompanied by a coronal mass ejection, but scientists said that its trajectory is offset from Earth and is unlikely to trigger major geomagnetic disturbances.
Launched on December 27 last year from the Xichang Satellite Launch Center in the southwestern province of Sichuan, Fengyun-4C is currently the world's most capable geostationary meteorological satellite when it comes to comprehensive single-satellite detection capabilities.
It can significantly enhance the monitoring of meso- and small-scale weather systems and early warning capabilities regarding such systems, as well as the monitoring of space weather sources, thus strengthening its role as the first line of defense in meteorological disaster prevention and mitigation.

UN Secretary-General Antonio Guterres on Monday called for engagement and cooperation of relevant parties for a confidence-building mechanism that aims to safeguard the movement of essential goods through maritime choke points.
Guterres said a task force he established in March for the Strait of Hormuz crisis has worked to develop "a practical and time-bound confidence-building mechanism focused initially on fertilizers and related raw materials -- but with the ability to be extended to other products."
"Navigational rights and freedoms are not abstract principles, they are international law. Those rights and freedoms are vital for international peace and security and for the flow of food, energy and essential goods on which billions of lives depend. The mechanism would not authorize passage through the State of Hormuz or alter the rights or obligations of any Member State and their international law. Sovereign decisions remain entirely with participating Member States. United Nations would serve as a neutral facilitator and the purpose is simple to reduce immediate risks, support more orderly and predictable transit, and help rebuild the confidence necessary for diplomacy and de-escalation," he stated at a press briefing.
The mechanism can be operationalized quickly as international support for this effort has been encouraging, particularly from vulnerable countries that understand what is at stake when maritime lifelines are disrupted, he said. "What is needed now is the cooperation and political will of the parties. I urge all concerned to engage seriously and constructively."
Guterres cautioned that the mechanism is not a substitute for fully restoring navigational rights and freedoms, or for the political solutions needed to end these conflicts. But it is a practical first step. A demonstration that, even amid conflict, it is possible to reduce risks, protect civilians and safeguard the movement of essential goods, said Guterres.
"The alternative is continued disruption, deeper mistrust and mounting hardship for people far beyond the regions directly affected," he warned.
Guterres called for full respect for international law, including the law of the sea and international humanitarian law; protection for civilian shipping, infrastructure and civilian seafarers; the upholding of navigational rights and freedoms; an immediate end to attacks against commercial shipping and civilian infrastructure in the Black Sea; the full restoration and respect of navigational rights and freedoms in the Strait of Hormuz; and an end to attacks against shipping in the Red Sea and around Bab al-Mandab.
"Maritime choke points must never become instruments of coercion. And the world's food supply must never become collateral damage of conflict," said Guterres.
