Nov. 5 (UPI) — A moderate solar flare might affect radio communications on Earth Wednesday after a pair of powerful solar flares disrupted radio communications in sunlit areas of the globe this week, the National Oceanic and Atmospheric Administration said.<\/p>\n

NOAA’s Space Weather Prediction Center said it recorded a moderate solar flare at 6:19 a.m. EST Wednesday from the sun’s AR 4274 region, but it is weaker than the two reported on Tuesday<\/a>.\n<\/p>\n

Wednesday’s solar flare has produced a partial halo coronal mass ejection that might “have some Earth-directed component to it,” the SWPC said<\/a>.<\/p>\n

“This CME is currently under analysis to determine any Earth-directed threat and, if so, what level of geomagnetic response we might anticipate,” the center added.\n<\/p>\n

Two larger solar flares on Tuesday disrupted radio communications in North and South America and from the North Pacific Ocean to Australia.<\/p>\n

The first occurred at 12:34 p.m. EST from sunspot AR4274, which disrupted radio communications in most sunlit areas of North and South America, according to Space.com<\/a>.<\/p>\n

A second solar flare occurred at 5:02 p.m. from a hidden area of the sun’s southeastern region and was weaker than the first.\n<\/p>\n

That flare caused a radio blackout across sunlit areas of the North Pacific Ocean to New Zealand and some of eastern Australia.<\/p>\n

Each solar flare released large plumes of magnetized plasma called coronal mass ejections that are not headed toward Earth, but their outer edges could interact with a solar wind that is moving fast and is predicted to cause geomagnetic storm conditions on Thursday and Friday.<\/p>\n

A solar flare is a large eruption of electromagnetic radiation from the sun and can last several minutes up to several hours.<\/p>\n

The sudden burst of electromagnetic energy travels at the speed of light and affects sunlit areas on Earth almost immediately upon eruption.<\/p>\n

Such solar storms can produce more vibrant auroras during the nighttime hours, according to Space.com.<\/p>\n","protected":false},"excerpt":{"rendered":"A trio of solar flares, similar to the one pictured from 2012, erupted from the sun this week,…\n","protected":false},"author":2,"featured_media":265038,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[64,63,128,285],"class_list":{"0":"post-265037","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-au","9":"tag-australia","10":"tag-science","11":"tag-space"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/265037","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=265037"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/265037\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/265038"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=265037"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=265037"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=265037"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
