  • Moon through Anvil

  • One fine evening in Scotts Bluff National Monument, after presumably its last lightning activity, a weakening supercell floated overhead, its anvil translucent to the waxing moon.  The surrounding landscape of sandstone and ash bluffs took on the blended hue of refracted moonlight from above and town lights of Scottsbluff an[...]
  • Total Solar Eclipse 2017

  • At age six, looking at a map of future solar totalities in the World Book Encyclopedia, I had the High Plains part of the path in the crosshairs.  Elke and I each have been waiting our whole lives for this, decades since childhood, so it's fitting that we did it together.  After a lifetime, we finally witnessed one of the mo[...]
  • Lunar Crepusculars

  • Altocumulus clouds passing in front of the moon split its light into crepuscular rays, visible as well to eye as to camera exposure, thanks to the very rural setting devoid of more than isolated artificial light. 10 S North Platte NE (23 Jun 10) Looking SW 40.9889, -100.764
  • Lunar Corona

  • A broken, diffuse altocumulus deck put on a colorful show of nocturnal atmospheric optics during the cool, pre-dawn hours.  Coronas come to the eye by means of optical diffraction (bending of light) through small water droplets of the clouds.  I enjoyed this corona more than most because the cloud layer moving quickly and wa[...]
  • Mooney Sunrise

  • Taking in a glorious sunrise from one side of the sky to the other, I realized that soon a rather unconventional composition soon would avail itself—dawn's half moon bathed in soft, feathery, coral-pink translucence of sunrise cirrus.  Time for the zoom lens, quickly!

  • Super Blood Harvest Moon Tetrad

  • My admittedly ridiculous title combines the best (or worst!) of many nicknames for the uncommon juxtaposition of a so-called "super moon" (in its closest orbital segment to Earth), "blood moon" (red light refracted through Earth's atmosphere then reflected off the lunar surface), tetrad (fourth straight lunar eclipse that ha[...]
  • Baily's Beads

  • On the other side of an annular eclipse from the first crescent sun, the visual edges of the lunar and solar discs became juxtaposed, rendering a beaded edge for just a few seconds.  This phenomenon, which also shows up during total solar eclipses, is known as Baily's beads after its 1836 documentation by Francis Baily.  The[...]
  • Crescent Sun

  • What a treat it was to be able to set up along the High Plains of the Texas-New Mexico border for the 2012 annular eclipse, the day after a great supercell and lightning show in western Oklahoma!  In an annular eclipse, the moon is far enough away from Earth in its orbit that its apparent diameter is smaller than that of the[...]
  • Comet Pan-STARRS, Okie Smoke and a Crescent Moon

  • In late twilight sky, the faint Pan-STARRS comet lines up near a very newly waxing crescent moon, the shaded side nicely bathed in earthshine, all behind assorted layers of smoke from several wildfires burning across portions of Oklahoma, reddened before the horizon's twilight glow.  The comet was unusual enough, but the com[...]
