[漢羅] 活跳太陽 ê 太陽烏子

是按怎咱 ê 太陽 這馬會遮爾活跳跳？ 無人知影。 太陽表面活動增加是本底就知--ê，因為 伊 這馬是愈來愈倚 2025 年 ê 太陽極大期。 毋過，頂個月咱 ê 太陽 puh--出來 ê 太陽烏子，比過去 11 年 ê 太陽週期 任何一個月攏閣較濟，甚至會當算到 2002 年去。 這張相片 是 kā 今年 1 月 到 6 月 用 NASA 動力學天文台衛星 逐工翕 ê 相片疊做一張--ê。 這內底有足濟太陽烏子，其中較大粒 ê，tī 太陽盤頂懸會出現 2 禮拜，ùi 倒爿行到正爿。 太陽週期繼續，咱就會看著太陽烏子較捷出現 tī 赤道 附近。 太陽烏子是太陽表面活動 ê 其中一款，其他閣有 太陽 爍光 kah 太陽日冕噴出 (CMEs)，這會 kā 粒子擲入去 太陽系 內底。 因為這寡粒子會影響太空人 kah 電子設備，所以追蹤太陽表面 ê 變化就毋是干焦為著 藝術價值 矣。 是講，太陽活動 嘛會當是有足懸 ê 藝術價值，尤其伊若是咧逐發生 tī 地球大氣層 ê 極光。

[English] Sunspots on an Active Sun

Why is our Sun so active now? No one is sure. An increase in surface activity was expected because our Sun is approaching solar maximum in 2025. However, last month our Sun sprouted more sunspots than in any month during the entire previous 11-year solar cycle -- and even dating back to 2002. The featured picture is a composite of images taken every day from January to June by NASA's Solar Dynamic Observatory. Showing a high abundance of sunspots, large individual spots can be tracked across the Sun's disk, left to right, over about two weeks. As a solar cycle continues, sunspots typically appear closer to the equator. Sunspots are just one way that our Sun displays surface activity -- another is flares and coronal mass ejections (CMEs) that expel particles out into the Solar System. Since these particles can affect astronauts and electronics, tracking surface disturbances is of more than aesthetic value. Conversely, solar activity can have very high aesthetic value -- in the Earth's atmosphere when they trigger aurora.
