A restless Earth-facing sunspot unleashed a powerful X-class solar flare on June 30, triggering radio blackouts across parts of North America.<\/p>\n

The X1.1 solar flare<\/a> erupted from sunspot region AR4479, peaking at 4:50 p.m. EDT (2050 GMT) according to NOAA’s Space Weather Prediction Center.<\/a><\/p>\n

<\/p>\n

The intense burst of X-rays released during the eruption reached Earth in just over 8 minutes, triggering strong (R3) radio blackouts across the daylight side of Earth<\/a>. This mainly affected high-frequency radio users across parts of North America who may have experienced temporary signal degradation or brief communication outages while the flare was at its strongest.<\/p>\n

The eruption also launched a coronal mass ejection<\/a> (CME) \u2014 a huge cloud of magnetized solar plasma hurled into space. When Earth-directed, CMEs can collide with our planet’s magnetic field and spark geomagnetic storms, which subsequently can produce dazzling northern lights<\/a> displays.<\/p>\n

This one, however, appears unlikely to pack much of a punch.<\/p>\n

Early observations suggest the CME is traveling mostly northward, with only limited Earth-directed material. We may experience a glancing blow around July 3.<\/p>\n

While forecasters will continue analysing imagery and models over the coming days, the eruption isn’t currently expected to produce a significant geomagnetic storm or widespread aurora display.<\/p>\n

Solar flares are sudden bursts of energy released when magnetic fields around sunspots<\/a> become twisted and reconnect. They are ranked using five classes \u2014 A, B, C, M and X \u2014 with X-class flares representing the most powerful eruptions.<\/p>\n

What are CMEs? <\/p>\n

CMEs behave a little differently. Unlike the radiation from a solar flare, which reaches Earth at the speed of light<\/a>, these clouds of charged particles typically take one to three days to reach us. If they arrive in the right magnetic orientation, they can disturb Earth’s magnetic field<\/a> and trigger geomagnetic storm conditions.<\/p>\n

Will we see the northern lights?<\/p>\n

With the Fourth of July just days away, an Earth-directed CME could have set the stage for a different kind of fireworks display. Instead, early observations suggest this eruption will deliver little more than a glancing blow to Earth around July 3, if that.<\/p>\n

As things stand, significant geomagnetic storm conditions are unlikely to develop, meaning the chances of widespread northern lights are low.<\/p>\n

The good news for aurora chasers is that AR4479 is still facing Earth. If the restless sunspot unleashes another flare and a better-aimed CME over the next few days, the outlook could rapidly change. Space weather forecasters are keeping a close eye on the region!<\/p>\n","protected":false},"excerpt":{"rendered":"A restless Earth-facing sunspot unleashed a powerful X-class solar flare on June 30, triggering radio blackouts across parts…\n","protected":false},"author":2,"featured_media":519796,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[85,46,141,145],"class_list":["post-519795","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-il","tag-israel","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/519795","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=519795"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/519795\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/519796"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=519795"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=519795"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=519795"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
