每早晨，這都是新的 - 春分以來四天的日出 ... "It's new every morning" - sunrise on four consecutive days after vernal equinox

(With English at the bottom)
本以為三月份的日出沒有秋冬般壯觀，想不到在寒流後21/3天色奇特；

22/3雲的形狀驚喜，太陽大為縮小、23/3見金蛋、24/3旭日矇矓。

原來在能見度、透光度影響下，太陽面貌如此多變！

A gold light sketched across the sky
一道金光劃過長空

As clouds reduced sunlight, the sun became a small light dot.
The zigzag shaped gap within the clouds
created an interesting sight.
可能有雲減弱光線，太陽變成小光點
雲間有之字形空隙，奇特有趣

金蛋

24.3.2018     7:18 a.m.
The smog reduced the size of the sun considerably.
霧霾下太陽矇矓，也大為縮小

連日拍攝下，開始留意到照片時間，

以及太陽與山峰相對位置。

但為何白日時大時細、時高時矮、

出現的時間一天比一天遲？

21.3.2018     7:43 a.m.

22.3.2018     7:49 a.m.

23.3.2018     7:50 a.m.

24.32018     8:04 a.m.

原來太陽移動的軌跡每天都在變化，

移動路徑每天靠左些及升高些，因此位置每天不停變動；

若陽光受雲或霧霾煙霞影響透光度，太陽會縮小！

3月9日拍攝陽光耀山頂(下圖)

但如上圖所示，春分及其後三天的太陽，

未見在峰頂散發光芒，

那麼為甚麼3月9日卻有此現象？

這才更懂得感恩，原來「金頂」如此珍貴！

若想再見，要等半年後了！

9.3.2018     7:17 a.m.

因此推斷出現「金頂」，

可能是因為太陽中央照射峰頂才會形成。

但春分以來這四天，太陽的位置已高出山峰不少，因此「金頂」不再現。

所以一切在於掌握時間、把握上天所賜機會！

曾在去年10月10日首次拍攝類似「金頂」的情況，

但旭日被雲遮擋，視乎雲的形態與位置，效果便如此不同：

"It's new every morning" - sunrise on 4 days after vernal equinox

Sunrise on 21, 22, 23, and 24 March were captured and compared.

It’s interesting to see the position and size of the sun 

varied so much within four consecutive days!

What were the reasons behind this phenomenon?

In fact, it demonstrated that the position of the sun is new every morning, 

as it is moving leftward and higher up every day after vernal equinox, 

when the sun shines directly on the Equator and is 

‘moving up’ along the Northern Hemisphere on the globe.

The size of the sun also depends on visibility,

which is affected by clouds, fog or smog.

Sunrise is really new every morning!

Another interesting observation was that the summit 

was not brightly lit as the photo taken on 9 March presented. 

It was probably because the centre of the sun 

leveled with the summit within those days. 

But it also required a good visibility to show up.

So I then realized how grateful I should be 

as I had captured it on 9 March, 

because in order to see this sight again, 

I need to wait for another half-year’s time!

The first time when I saw the summit brightly lit was on 10 Oct 2017,

but as the clouds shaded the sun on that day, 

the visual effect was so different.
