著名活動區迴歸的太陽 X 耀斑
Solar X Flare as Famous Active Region Returns
發表日期：2024-05-28
它回來了本月初曾在地球周圍產生極光的著名太陽活動區域，在繞太陽遠側旋轉後倖存了下來--並且回來了。 昨天，當它開始重新出現在面向地球的一側時，這個以前被標為 AR 3664 的區域又丟擲了一個大的太陽耀斑，又是能量最高的 X 級範圍。這段影片顯示了左下方新出現的活躍區域，它是由 NASA 的地球軌道太陽動力學天文臺昨天用紫外線拍攝的。該影片是整個太陽旋轉 24 小時的延時攝影。 仔細觀察左下方大約 2 秒鐘處的區域，可以看到爆發出的強大耀斑。預計耀斑和相關的集合放射粒子產生的高能粒子不會直接撞擊地球，也不會引發令人印象深刻的極光，但科學家們將在未來兩週內密切關注這個異常活躍的區域，因為它正對著地球，看看會發生什麼變化。
原文：It's back. The famous active region on the Sun that created auroras visible around the Earth earlier this month has survived its rotation around the far side of the Sun -- and returned. Yesterday, as it was beginning to reappear on the Earth-facing side, the region formerly labeled AR 3664 threw another major solar flare, again in the highest-energy X-class range. The featured video shows the emerging active region on the lower left, as it was captured by NASA's Earth-orbiting Solar Dynamics Observatory yesterday in ultraviolet light. The video is a time-lapse of the entire Sun rotating over 24 hours. Watch the lower-left region carefully at about the 2-second mark to see the powerful flare burst out. The energetic particles from that flare and associated CME are not expected to directly impact the Earth and trigger impressive auroras, but scientists will keep a close watch on this unusually active region over the next two weeks, as it faces the Earth, to see what develops.
