And next, on a rough gravel road, we're all amazed to see parallel shadow bands
- westward-undulating stopped-down slits of sunlight diffracting through the upper atmosphere - in unexpectedly high contrast.
"The coming of the sudden shadow," the approach of the umbra, shadow bands
, Baily's Beads, the chromo-sphere and flash spectrum, totality, the corona, "the eye of God," coronal loops and streamers, darkness at midday, the "360[degrees] sunset," the (ruby-red) solar prominences, the eclipse wind (and temperature drop), planets and stars visible in a midday sky of midnight blue--and what I take to be the most staggering sight in all of astronomy: the diamond ring.
''All of the various things that you're supposed to see -- the shadow bands
, the corona, both diamond rings, prominences -- it had everything.
As there was thin high cloud during the event, images were obtained showing shadow bands
projected on to this high cloud.
Careful observation may show shadow bands
, caused by atmospheric turbulence, shimmering across the ground.
Because of the repetitive nature of these polymorphic structures, PCR amplification often leads to so-called "shadow bands
" resulting from DNA polymerase slippage.
When the moon has nearly positioned itself in the sun's path, shadow bands
will be seen - the atmospheric equivalent of ripples when the sun is seen from under water.
"Watch for shadow bands
!" someone else calls, with about five minutes of light remaining.
"[A] peculiar phenomenon seen at an eclipse are shadow bands
were clearly seen just before and after totality against a white sheet laid over the ground.
The repeat length detection requires radioactive analysis or silver staining of polyacrylamide gels, which produces several shadow bands
around the main allele band due to the nature of the repeat amplifications.
The app also includes announcements of interesting occurrences during the eclipse, such as temperature changes, wildlife behavior, and where to look for shadow bands
. A demo total eclipse movie, synchronized with timers, is included to help users practice their photographic technique well before the event.
