We
had a good view of TLE 2018 this morning from (my back yard) in Tucson
Arizona, with cooperative clear skies. Well, at least the “first
half” of the eclipse as we ‘lost’ the Moon (as expected) as it
descended into the shrubbery as morning twilight encroached. Our
last view before arboreal obscuration was at about 6:25 AM MST.
From here, partial ingress began with the Moon 30 degrees above the
(true, not arboreal) horizon, and totality began with it (only) 17
degrees up. The low altitude of the Moon as totality progressed
lead, to slightly degraded viewing (at highest air-mass) at our last
unobscured look just before mid-eclipse, but non-the-less it was a very
pretty sight.
The above photomosaic shows the of the progression of the eclipse as
seen from here. Imaged with a 3.5-inch Questar and Nikon D3000 camera
from top-left at 4:48 AM MST (three minutes before the end of the
penumbral ingress) until trees became problematic soon after the last
frame (bottom-right) was taken at 6:23 MST (7 minutes before
mid-eclipse). This sequence of images is on close to 5-minute
centers for nearly all frames (with some gitches in that timing for a
few frames, but close to that). In this rendering I tried,
best I could, to preserve/reproduce both the coloration, hue, and
saturation of the moon during totality as it appeared to me in my minds
eye with 20x80 binoculars in this rendering. That to see seemed a
bit muted, not the “blood” red that some have commented on
descriptively. In any event, that is the first mosaic.
Below are is just a few of the same frames, but among them some
stretched to better see some of the color and brightness gradients near
the second contact limb. Visually, I could manage to see visually
(in the binos) the bluish stratospheric-ozone-filtered stratum soon
before totality - though didn’t capture it very well in images this
time. Though this does appears right on the limb in the bottom
right of the second mosaic right after entering there into the Earth's
umbra, though it is subtle.
