This charged gas moves, generating a powerful magnetic field.\u00a0<\/li>\n<li>The\u00a0sun\u00a0goes through a natural solar cycle approximately\u00a0every 11 years.<\/li>\n<li>Over the course of 11 years, the\u00a0magnetic field between the Sun\u2019s northern and southern hemispheres winds up\u00a0until it becomes so dense that\u00a0the hemispheres flip. The north hemisphere becomes the south, and vice versa.<\/li>\n<li>This flipping point marks the Solar Maximum. It\u00a0occurs approximately halfway\u00a0through the solar cycle.<\/li>\n<li>It\u2019s\u00a0associated with a greater number of sunspots observable on the surface of the sun.<\/li>\n<li>By contrast, the\u00a0Solar Minimum, which\u00a0marks the beginning and end of each\u00a0Solar Cycle, has fewer sunspots.<\/li>\n<li>As the sun approaches the solar maximum, we see\u00a0more brilliant explosions, dark\u00a0sunspots, loops of plasma, and swirls of super-hot gas.<\/li>\n<li>Impacts:\n<ul>\n<li>This increased solar activity can cause\u00a0extreme space weather events, including\u00a0solar flares and eruptions.\u00a0<\/li>\n<li>It can also\u00a0disrupt radio communications\u00a0and the\u00a0power grid and have serious health\u00a0consequences for astronauts.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2>What are Sunspots?<\/h2>\n<ul>\n<li>Sunspots are\u00a0dark, planet-size regions of strong magnetic fields on the surface of the sun.<\/li>\n<li>Sunspots\u00a0form when concentrations of magnetic field\u00a0from deep within the sun\u00a0well up to the surface.<\/li>\n<li>They consist of a\u00a0central darker region,\u00a0known as the\u00a0umbra, and a surrounding region, known as\u00a0the penumbra.\u00a0<\/li>\n<li>They\u00a0can spawn eruptive disturbances such as\u00a0solar flares and coronal mass ejections (CMEs).\u00a0<\/li>\n<li>These regions of the sun\u00a0appear darker because they are\u00a0cooler than their surroundings.\u00a0<\/li>\n<li>The frequency and intensity of sunspots visible on the surface indicate the level of solar activity during the 11-year solar cycle, that is driven by the sun&#8217;s magnetic field.\u00a0<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What are Solar Flares?<\/h3>\n<p>These are magnetic plasma ejected at great speed from the solar surface. They occur during the release of magnetic energy associated with sunspots (\u2018dark\u2019 regions on the Sun that are cooler than the surrounding photosphere), and can last for a few minutes or hours. These flares can be divided into various categories based on their brightness in X-ray wavelengths There are five different classes of solar flares: A, B, C, M, and X. Each class is at least ten times more potent than the one before it.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.space.com\/sun-surface-solar-maximum-approaches-photo\" target=\"_blank\" rel=\"nofollow noopener\"><u>See the sun&#8217;s surface rage as solar maximum approaches (photo)<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Solar Maximum associated with a greater number of sunspots observable on the surface of the sun.<\/p>\n","protected":false},"author":5,"featured_media":20752,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-20751","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/20751","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=20751"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/20751\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/20752"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=20751"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=20751"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=20751"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
