Partly cloudy and a dirty dome on my allsky camera limited the ‘awe’, but you can still certainly tell that our Moon is diminishing in brightness ( and going ‘dark’ ) in this time lapse. Pay attention to the timestamp at the top left corner of the screen.

Here are the key times:

  • 02:48 – First contact of Earth’s penumbra ( starting partial block of the Sun’s light )
  • 03:45 – First contact of Earth’s umbra ( the darkest part of the shadow )
  • 05:11 – Totality begins
  • 05:19 – Mid-point of Totality
  • 05:25 – Totality ends
  • 06:13 – Sunrise

Wow, That was amazing. I had to watch it several times to spot the different segments during the key times. The moon totally went dark or disappeared right in front of the camera.

    Ya, the camera exposure was adapting to the loss of light for the first bit, so it made it harder to recognize ( the exposure time is also in the upper left corner ). Considering the clouds and dirt on the dome, I’m well pleased with the result.. šŸ™‚
