I see we have a full lunar eclipse coming on Feb 20/21 (depending where you live).
I know that even during a full eclipse the Moon is still visible with a coppery hue, due to the refraction of light around the Earth. Now that we have a bunch of probes in orbit of the Moon, is there any plan / is it possible to take an image of the Earth from the Moon during totality? (or has this already been done?) I would think that a picture of the Earth surrounded by a red ring would be amazing! |

The eclipse began under a rare rainy sky in Palm Springs, Calif., and as totality began I dispaired of seeing the event. The skies then cleared about a third of the way through totality and I set up my 6 inch reflector, binocculars, video camera and drawing stuff. I hastily drew isophotes on a set of printed out full moon images within which color and brightness information could be noted, using the WWV time signal.
I notice again the tendency of even excellent digital camera pictures to shift the color balance toward garish oranges and reds. The reality as seen by at least this pair of eyes is more subtle and varied. I used the video later to help in drawing the tonal values within the shadow. This eclipse, at least starting at mid totality, appeared fairly muted in the intensity and range of colors within the Earth shadow. The southern portion near the shadow boundary was a light golden yellow, and the eastern part of the disk displayed a nice spectral gradation to muted orange and duller rusty red. The western Moon shadow colors at that time were less saturated, duller, with a sharper gradation to the dark brown shadow core, or umbra region. The brighter western colors faded in the latter part of totality, and a pale gray lighting appeared along the SW limb, displaced N from the closest part of the shadow edge, shortly before totality ended. As the sunlit Moon returned the shadow colors moved off the disk and faded in the brightning sky. (P.S. I'm having trouble uploading an image file-it never stops telling me it's uploading) Don |
