HKO weather forecast for coming week:

Himawari 9 link


Forecast 


3 scenarios basically cover almost all normal possible outcomes , to east, to west, or just weaken

現時持續影響本港的高溫天氣將隨著下週驟雨增多而有所緩解，而下週南海的低壓系統活動亦轉趨活躍。

第一個低壓系統進入南海後強度較弱，距離廣東沿岸較遠，但與其相關的高空擾動會在下星期一及星期二（9月15及16日）為廣東沿岸帶來驟雨及雷暴。

第二個低壓系統進入南海後距離廣東沿岸較近，不同預報模式的強度及路徑存在分歧。但隨著該低壓系統在下週中後期向北靠近廣東沿岸，該區天氣漸轉不穩定，驟雨亦會增多。

第三個潛在低壓系統與上述兩個系統相比強度最高，會於下週末期間靠近台灣至呂宋海峽一帶，是否進入南海仍有變數。

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
