New Delhi: The sun unleashed a massive solar flare on Wednesday, which has the potential to impact satellite communications and global positioning systems, the Centre of Excellence in Space Sciences India (CESSI<\/a>) said. \"The X2.2 class solar flare eruption took place at 3:57 UTC (9.27 IST) from the solar magnetic active region AR12992,\" Dibyendu Nandi, Associate Professor and Coordinator of CESSI<\/a> at the Indian Institute of Science Education and Research<\/a>, Kolkata told PTI.

Solar flares are powerful bursts of energy that can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X-Class which denotes the most intense flares, while the number provides more information about its strength.

\"Strong ionospheric perturbation is ongoing over India, South East Asia and the Asia-Pacific regions. Expected high frequency communication blackouts, satellite anomalies, GPS scintillations, airline communication impacts,\" the CESSI said on Twitter.

Nandi said the CESSI had predicted the eruption of an X-Class flare on April 18. He said the scientists at CESSI were studying the impact of the flare.

According to NASA<\/a>, the biggest flares are known as 'X-class flares' based on a classification system that divides solar flares according to their strength.

The smallest ones are A-class (near background levels), followed by B, C, M and X, it said.

According to NASA<\/a>, similar to the Richter scale for earthquakes, each letter represents a 10-fold increase in energy output. An X class flare is ten times an M class eruption and 100 times a C class flare.<\/body>","next_sibling":[{"msid":90955317,"title":"Nokia says ready to jointly develop 5G private networks with Indian enterprises","entity_type":"ARTICLE","link":"\/news\/nokia-says-ready-to-jointly-develop-5g-private-networks-with-indian-enterprises\/90955317","category_name":null,"category_name_seo":"telecomnews"}],"related_content":[],"msid":90956500,"entity_type":"ARTICLE","title":"Sun emits massive solar flare with potential to impact satellite communications: CESSI","synopsis":"Solar flares are powerful bursts of energy that can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.","titleseo":"telecomnews\/sun-emits-massive-solar-flare-with-potential-to-impact-satellite-communications-cessi","status":"ACTIVE","authors":[],"Alttitle":{"minfo":""},"artag":"PTI","artdate":"2022-04-20 14:55:47","lastupd":"2022-04-20 15:13:26","breadcrumbTags":["spacecom","satcom","cessi","research","industry","nasa","X class flares"],"secinfo":{"seolocation":"telecomnews\/sun-emits-massive-solar-flare-with-potential-to-impact-satellite-communications-cessi"}}" data-authors="[" "]" data-category-name="" data-category_id="" data-date="2022-04-20" data-index="article_1">

太阳发出巨大的太阳耀斑与潜在影响卫星通信:CESSI

太阳耀斑是强大的能量爆发,可以影响无线电通讯、电力电网、导航信号,对飞船和宇航员构成风险。

新德里:太阳释放出一个巨大的太阳耀斑周三,这有可能影响卫星通信和全球定位系统,在印度空间科学卓越中心(CESSI)说。“X2.2类太阳耀斑爆发发生在3:57 UTC(9.27是)从太阳磁AR12992活跃地区,“Dibyendu南帝,副教授和协调员CESSI印度理工学院的科学教育研究,加尔各答对PTI说。

太阳耀斑是强大的能量爆发,可以影响无线电通讯、电力电网、导航信号,对飞船和宇航员构成风险。

这次耀斑被列为一个x级表示最强烈的耀斑,而提供了更多关于它的力量的信息。

“强有力的电离层扰动持续在印度、东南亚和亚太地区。预期的高频交流停电、卫星异常、GPS闪烁,航空通信的影响,“CESSI在Twitter上说。

南帝说,CESSI预测x级耀斑的爆发在4月18日。他说,科学家们CESSI正在研究耀斑的影响。

根据美国国家航空航天局,最大的耀斑被称为“x级耀斑”基于一个分类系统,将太阳耀斑根据他们的力量。

最小的是a级(接近背景水平),紧随其后的是B, C、M和X,它说。

根据美国国家航空航天局,类似于里氏震级的地震,每个字母代表一个能量输出增加10倍。X级耀斑是十倍一个M类耀斑爆发和100次C类。
