Partial Lunar Eclipse, 2021-11-19

In the early morning hours of November 19th, 2021, the fully illuminated moon passed through the Earth’s shadow. The moon did not pass entirely into the shadow reaching 97% percent coverage at max eclipse. Hence, this was a partial lunar eclipse. The fact that the moon was near apogee, the farthest distance from Earth in its elliptical orbit, meant that the moon was at its smallest as viewed from Earth. This also meant that the time it took to traverse the shadow was maximized.

At moonrise, high clouds blocked the moon, and it appeared the after midnight eclipse could be obscured. However, clouds cleared for the most part during the 12:19 – 03:47 am eclipse timeframe. I used a Paramount MYT telescope mount with a Nikon Z6 camera and Sigma 600mm lens to record the event. I also used a 1.4x teleconverter so the focal length was 840mm. I chose to only record UHD video and occasionally ventured outside in the subfreezing air to look at the spectacle with my own eyes. It was an amazing sight with Orion not far away.

Below is a timelapse video from the video recording. I also made a timelapse of my four low-light surveillance cameras to show how the light dimmed during the eclipse. The third video is the complete real-time recording which I have placed in my “Simply Being There” playlist. If you want to just watch the event as it took place, you can sit back an do so.

I am grateful that the clouds cleared out, and that I was able to see this wonderful wonderful event. Enjoy

Sunset lightning in the South Dakota Badlands

On the evening of Saturday, 23 May 2020 a strong linear storm passed over the South Dakota Badlands. As the sun began to set, the stunning orange and pink light illuminated the backside of the storm and its trailing stratiform precipitation area. As is common with mesoscale convective systems, this backside region produced numerous horizontally extensive lightning flashes many of which contained positive cloud-to-ground return strokes. Also common with these types of flashes, negative leaders raced through the layered positive charge regions above cloud base, while trailing positive leaders propagated below cloud base in trail of the negative leaders presumably through negative screening layer charge or negatively charge rain. This spectacular “spider” lightning is my personal favorite and this spectacle was one I will not soon forget. My daughter and I filmed the flashes with every camera we had available and the video below shows our best captures. Recordings were made from 30 to 1,500 images per second.
