美國太空總署日前發出 G2 地磁風暴預警（中等），其後更將等級提升至 G3（強）。 地磁風暴是太陽表面發生日冕物質拋射（coronal mass ejection, CME），帶電粒子以高速 （每秒600公里以上）到達地球後，受地球磁場影響集中在兩極並產生放電現象。衛星操作、通訊、發電、甚至電腦系統等都可能受到影響。今年2月，SpaceX 發射了 49 顆 Starlink 衛星後，由於遇到地磁風暴，有 40 顆衛星無法克服增加了的大氣阻力爬升至預定軌道，最後墜落地球燒毀，令 SpaceX 損失了 5000 萬美元。 地磁風暴在地球最為明顯的影響就是極光，特別是高緯度地區。加拿大北部於3月30日晚上、歐洲北部於3月31日清晨，或有機會觀看到極光現象。<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[4],"tags":[],"class_list":["post-3939","post","type-post","status-publish","format-standard","hentry","category-4"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3939","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/comments?post=3939"}],"version-history":[{"count":4,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3939\/revisions"}],"predecessor-version":[{"id":3955,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/posts\/3939\/revisions\/3955"}],"wp:attachment":[{"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/media?parent=3939"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/categories?post=3939"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.weather.org.hk\/news\/wp-json\/wp\/v2\/tags?post=3939"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
