Example 2:
有一個太陽活躍區編號AR1429(是由一團太陽黑子所組成的)在2012三月初,連著引發了數起太陽閃焰事件。根據 http://spaceweather.com/ 的報導,以下列出AR1429所引發的閃焰記錄。
M3-class solar flare on March 2, 2012
X1.1-class solar flare on March 5, 2012
X5-class solar flare on March 7, 2012
M6-class solar flare on March 9, 2012
M8-class solar flare on March 10, 2012
M7.9-class solar flare on March 13, 2012
AR1429 在3月9日通過中央子午線。因此3月10日起,地表接收到 21 and 28 MHz 的
太陽無線電波暴(簡稱:無線電暴) 。
AR1429 passed the center meridian on March 9, 2012.
Solar Radio Burst at 21 and 28 MHz was detected on the ground on March 10.

其中太陽閃焰強度可分為以下四級 B C M X(我的記憶方式“變成X” become X 移除母音eoe後,就是 B C M X)

where solar flare can be classified into the following four classes: B C M X (A way to remember it: BeCoMe X). More information on AR1429 can be found from the following website http://digitaljournal.com/article/320684
你也可以察看Mt. Wilson 150-Foot Solar Tower 測站所提供之手繪的AR1429 發展情形。
