Syzygy – the exact alignment of sun, earth, and moon with the earth in the middle so that the moon is caught completely in the earth’s shadow.
The transit of the moon through the full umbra shadow took almost an hour last night, while the partial shadow cast while the moon moved through the penumbra happened relatively quickly.
Why a blood red moon during the lunar eclipse? The Hudson Valley Geologist explains that short (especially blue) wavelengths of light are scattered by the earth’s atmosphere, leaving the longer, orange and red wavelengths to be bent and focused on the moon.
I hope you all got a chance to see this somewhat rare event — another lunar eclipse of a super moon (at its closest distance to the earth in its orbit) won’t happen again until 2033.
