The Full Frost Moon passed through Earth's shadow early Friday morning in a partial, nearly total lunar eclipse.

The partial eclipse was visible beginning at 2:18 a.m. and peaked at 4:03 a.m. It was visible until 5:45 a.m.

Eclipse color

the lunar eclipse early Friday morning, November 19, 2021 will be near total with 99.1% of the Moon moving through Earth's shadow

During the partial eclipse, the Moon appeared red. Just as sunsets here on Earth vary from pale yellow through orange to red, you can see these same colors in a lunar eclipse, because they are created by the same thing -- light passing through our atmosphere.

When the atmosphere is filled with particulates, shorter wave lengths of light (toward the blue end of the spectrum) are scattered and longer wave lengths (toward the red end) pass through. The more particulates there are (such as smoke from wildfires), the more intense the colors. The larger the particulates (such as volcanic ash), the redder the colors.

With more than 20 active volcanoes world wide including the Cumbre Vieja volcano on the Spanish island of La Palma in the Canary Islands, this lunar eclipse was more red colored than in past years.
