The Sun is currently in the active phase of its 11-year cycle<\/a> and is slowly waking up <\/a>from a prolonged slumber. And it\u2019s showing no signs of wanting to slow down.<\/p>\n

Over the past 12 hours, our host star has unleashed three violent solar flares\u2014intense, concentrated bursts of electromagnetic radiation\u2014two of which were classified as X-class<\/a> flares. NOAA\u2019s Space Weather Prediction Center flagged both instances as R3<\/a> events\u2014relatively powerful solar events capable of triggering widespread radio blackouts. The Sun erupted again this morning, producing a weaker, but still significant, M-class flare.<\/p>\n

Already, the two X-class flares have caused radio blackouts around South America, according to NOAA. But forecasters are bracing for more solar explosions over this week. As of now, experts are keeping a close eye on Region 4274<\/a>, a complex cluster of sunspots that fired off the M-class flare and one of the X-class flares.<\/p>\n

One concern is that the region is rotating into a more direct view of Earth; stellar features move from left to right from our perspective, with the region soon pointing straight at us like a shotgun. If it were to release more solar flares, the ensuing solar storm could have a greater impact on Earth\u2019s communications. Currently, NOAA\u2019s forecast for solar flares lies at 65% for M-class flares and 15% for the more severe X-class flares.<\/p>\n

\u201cThis region continues to be a solar flare threat and therefore the likelihood of continued R1-R2 events and even a chance for another R3 event remains throughout the week,\u201d reported<\/a> NOAA\u2019s Space Weather Prediction Center.<\/p>\n

Brace for solar impact <\/p>\n

When the Sun produces solar flares, experts check whether ensuing coronal mass ejections (CMEs)\u2014a barrage of magnetized plasma from solar activity\u2014have the potential to graze the Earth\u2019s magnetic field and cause anomalies in our planet\u2019s atmosphere. These anomalies can include disruptions to radio communications, GPS systems, and power grids, along with spectacular auroras.<\/p>\n

NOAA\u2019s forecast report<\/a> affirmed that CMEs associated with the two X-class flares weren\u2019t headed to Earth, although solar winds may later redirect some of this mass toward Earth\u2019s magnetic field. In an update<\/a> this morning, NOAA added that the CME from today\u2019s M-class solar flare does appear to be headed for Earth.<\/p>\n

In addition, we may see minor G1-class storms over the next couple days that interfere with high-latitude power systems and create faint auroras in the sky<\/a>.<\/p>\n

But also, don\u2019t freak out <\/p>\n

It\u2019s also possible that one of the X-class flares was stronger than initially measured. Because it came from a sunspot behind the Sun\u2019s limb, it was partially eclipsed by the edge of the solar disk, posited Tony Phillips of spaceweather.com<\/a>.<\/p>\n

That said, these flares aren\u2019t likely to cause anything like the plot of the 2013 film The Carrington Event<\/a>. Still, geomagnetic storms caused by solar activity can affect aviation, maritime, and satellite communications, so having some warning signs in advance is a huge plus, given the projected strength of these solar events.<\/p>\n

\u201cThere\u2019s no reason to think this activity will subside,\u201d Phillips wrote. \u201cThese sunspots have been flaring for weeks, producing multiple farside CMEs in late October. Now they are turning toward Earth.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"The Sun is currently in the active phase of its 11-year cycle and is slowly waking up from…\n","protected":false},"author":2,"featured_media":117196,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[42454,85,46,141,14468,145,9770],"class_list":{"0":"post-117195","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-coronal-mass-ejections","9":"tag-il","10":"tag-israel","11":"tag-science","12":"tag-solar-flares","13":"tag-space","14":"tag-space-weather"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/117195","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=117195"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/117195\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/117196"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=117195"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=117195"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=117195"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
