Penumbra started at around  1:24am but it was around 1:45am that they were able to start detecting the slight hint of penumbral shading though their images but visual shading started at around 2:15am. Umbra started more or less around 2:25am and the magnificent 3D view of the penumbral and umbral shadings were a sight to behold as the umbral shadings progressed. Midway through totality, one can see the bright coppery orange tint on the penumbra area as early as 2:50am.  As it enters totality at around 3:23am, the eclipsed Moon shows a bright orange tint in the early stage of totality . 

As it progressed towards maximum totality at around 4:13am, the bright light orange tint started to dimmed a bit and becomes dull orange through visual observation with naked eye, binoculars and telescopes.  Using telescopes and camera  lenses exposed for longer duration, the images came out as dark red orange which most of the people referred to it as the "Red Moon."  By this time, stars started to be visible as the  ALPers were able to witness 2 lunar occultation of HIP85703 and another magnitude 8 star.  ALPer Pejvac Parhizkari was able also to image a wide angle shot of the eclipse to include the Milky Way! Estimated  Danjon scale for this eclipse is more or less around 2.5 as amid its dull red tint, James reported that he can still see it through his camera viewfinder.

ALPers were able to observe the eclipse till around 5:00am before the Moon got covered by thick haze in the SW horizon.   They then started to packed up their equipment as well as get a customary group shot before they go home to get some rest as well as report for work :)  Aside from this, ALPers Armando Lee and James Kevin Ty were also interviewed by ABS-CBN news reporters.
