昨天的太陽黑子
(千萬別用肉眼或照相機直接看太陽,要用特製的鏡片或塑料膜片)
從2月3日起的本周是太陽黑子異常活動的時期,晚上也可能有異常的極光。有興趣的人別錯過機會。
NASA,美國國家航空航天局的昨天的太陽黑子照片(倒數第二張)裏有地球的大小, 可以和耀斑的大小比較(耀斑寬度比15個地球直還長)。

Sunspot region AR4366 is extremely active this week (beginning Feb. 3, 2026), unleashing numerous X-class and M-class solar flares. A massive X8.1 flare was recorded on Feb. 4, following an X4.2 blast. The region is 15 Earths wide and poses continued, high risks for further significant flares.
Key Activity Details:
- Active Region: AR4366 is currently the primary focus of activity, showing rapid, complex growth after rotating into view on Jan. 30, 2026.
- Flare Activity: The region has produced over 20+ M- and X-class flares, including 9 major X-class flares by Feb. 4, causing radio blackouts.
- Solar Storms: A Coronal Mass Ejection (CME) from an X8.1 flare is expected to graze Earth's magnetic field on February 5, potentially bringing minor to moderate aurora visibility.
- Forecast: Moderate-to-high (75%) chances for more M-class flares and 25% for X-class flares persist for Feb. 5–6.
Note: For safe viewing, use specialized solar filters on telescopes or binoculars, as this sunspot is large enough to be seen with proper, safe equipment.
