近日點就是地球離太陽上倚 ê 時陣。 2023 年 ê 近日點 是發生 tī 世界時 (UTC) 1 月 4 號 16:17。 這張清楚 ê 太陽盤影像，是望遠鏡鬥 H-α 濾光片 tī 澳洲 雪梨 翕--ê。 這張相片翕了了後 免 24 點鐘，地球就行到近日點。 H-α 濾光片 會 予 水素原子發出 ê 特別紅光 透過來。 這張太陽相片強調 ê 是太陽 ê 色球層，這是 tī 光球層 ê 頂懸層，嘛是平常時咱看著 ê 太陽表面。 太陽烏子 ê 寸尺 kah 行星是差不多大。 Tī 這張 活跳太陽 ê H-α 影像內底，烏子區附近較光 ê 斑，叫做譜斑。 你若是注意看太陽邊界，就會看著本底 tī 太陽盤表面 彎彎曲曲 ê 烏暗電漿絲，離開太陽邊界了後 就會變做光 iàⁿ-iàⁿ ê 日珥矣。

[English] Perihelion Sun 2023

Perihelion for 2023, Earth's closest approach to the Sun, was on January 4 at 16:17 UTC. That was less than 24 hours after this sharp image of the Sun's disk was recorded with telescope and H-alpha filter from Sidney, Australia, planet Earth. An H-alpha filter transmits a characteristic red light from hydrogen atoms. In views of the Sun it emphasizes the Sun's chromosphere, a region just above the solar photosphere or normally visible solar surface. In this H-alpha image of the increasingly active Sun planet-sized sunspot regions are dominated by bright splotches called plages. Dark filaments of plasma snaking across the solar disk transition to bright prominences when seen above the solar limb.
