不經不覺，期待一年的努力有了成果，這個撇除陰天和下雨日子(今年都幾多！)，要求約每星期同時間(我選了上午七時半上班前)拍一至兩天的 project, 話易又不易，說難又不太難，但在好奇心驅使看“最期待的画面”大前題下，在本年「冬至」來到後，終於看到香港版太陽8字日行跡和太陽在廿四節氣的位置！

拍攝這令我更了解大自然的奥妙，知道太陽在「冬至」移到最南(日至南)，「夏至」移到最北，二分(「春分」，「秋分」)時太陽(約)在正東升起，正西落下。亦為攝影朋友為何夏丶冬季會說太陽「唔啱位」影響攝影構圖的原因。

祝各位冬至及聖誕快樂，2015 新年進步！

The figure-8 shaped curve was taken as the path of the Sun at 07:30am (HKT, UTC+8) in the year 2014, highlighting with the 24 solar terms.
Due to cloudy or rainy days, the image may be taken before / after the solar term day and are marked +/- nd(ays).
That year's two equinoxes on March 21 (0° longitude) and September 23 (180° longitude) correspond to the mid-points but not the cross-over point, on the curve.
While summer solstice on June 21(90° longitude) and winter solstice on December 22 (270° longitude) are located at the top-left and bottom-right on the curve respectively.

Wish you a Merry Christmas and a Happy New Year 2015 !
