Partial Lunar Eclipse of November 19, 2021.

Jeremy Veldman and Brian Hancock observe the Partial Lunar Eclipse (97% Total) of November 19, 2021. We chose to observe the eclipse from Burton’s Sugar Farm- the MAS dark sky site- so that we could observe the changes in the sky brightness and contrast in the landscape, as the moon reached mid-eclipse. We also took SQM sky readings before the penumbral phase, before first contact with the umbra, and at mid-eclipse, to compare sky quality brightness as the eclipse progressed. We observed a considerable change in the sky brightness as mid-eclipse approached, and the sky got considerably darker. We also wanted to see where the eclipsed moon would fall on the Danjon Scale- a five-point scale proposed by French Astronomer André-Louis Danjon in 1921 for measuring the appearance and luminosity of the Moon during a total lunar eclipse. We show the SQM measurements and Danjon Scale at the end of the video.

From Burton’s Sugar Farm, near Michigan City, MS. November 19, 2021. 12am – 5am, CST.

1:18am – beginning of Umbra phase
3:03am – maximum eclipse
4:47am – end of eclipse
