Blood Moon

Subject: Moon during total lunar eclipse
Camera: Canon Rebel T1i

I was lucky enough to have a clear night for tonight’s total lunar eclipse. I snapped a few single shots of the moon in umbra and penumbra of the earth’s shadow for comparison as well as a wide shot of the moon and Mars. It would have been better for me to take a video and stack the frames for clearer shots, but apparently 3am is too late for me to think about these sorts of things.





For those of you who saw the eclipse with your own eyes, you probably noticed the red hue the moon took when completely obscured by the earth’s shadow. This is due to the way the last little bit of sunlight passes through the earth’s atmosphere before reaching the moon. If you were to imagine yourself standing on the moon while the eclipse occured, you would see a glow of the sun’s light around the earth. This light acts like an enormous sunset around the entire horizon encompassing the earth resulting in red-orange light much like what we see when the rises or sets in the morning or evening.


In the image below you can see Mars in the upper right portion of the photo.

This total lunar eclipse is the first in a tetrad of four lunar eclipses occurring in the next 18 months due to the fortunate alignment of the moon’s orbital plane and that of the earth with the sun.

(Also, for those of you waiting for a solar eclipse, an annular solar eclipse will be aligned perfectly for the San Antonio area in October of 2023, and a total solar eclipse will be seen near us in the following year.)
