Summary:
On Aug. 7, 2008, Alaska's Kasatochi volcano erupted, hurling more
than a million tons of volcanic ash and sulfur dioxide into the
stratosphere. This produced unusually colorful sunrises and sunsets
around the northern hemisphere for months. Purple is one of the
telltale colors of a volcanic sunset. Fine volcanic aerosols in
the stratosphere scatter blue light which, when mixed with ordinary
sunset red, produces a violet hue. Other signs to look for include
a bright yellow "twilight
arch" and long crepuscular rays and shadows. |

This
fall, trees are not the only things displaying Halloween
colors. Tonight's volcanic aerosols could be seen 30 degrees
above western horizon just after sunset. The Ghost of Kasatochi
still haunts the skies above eastern Kansas. Canon Rebel

I
was on my way home from a beautiful night at the Welzheim
observatory, when I recognized even more beautiful colors
at the eastern horizon. I have seen hundreds of sunrises
in my life before at many places on earth. But the colors
I saw this morning were unlike any others. What a spectacular
show that was! The image has 104 degree angle horizontal
and 81 degree vertical, if that helps. An ultra wide angle
lens was used. More: Date + Time: Aug 31, 2008, 4:17 UT

EF 14mm/2.8 L wideangle lens Camera: Canon EOS 1Ds Mark

Details: Not much at all. The image respresent my visual
impression pretty good. No image can preserve my impression
at this scenery, can make the same goose skin I had. However,
nothing ventured, nothing gained. Thanks for looking. Cordially,

During
the past several days, the sunsets have become more dramatic.
Probably due to a change in the weather (cooler, less hazy
days) and the volcanic eruptions described in today's SW.
Each evening has provided me with a different experience.
Two cropped and reduced examples enclosed. Image0073 is
of rays taken on 8/20/2008; Image0112 is a sun pillar (near
left) with mammatus cloud-like features near the pillar
at 4 o'clock-just above the trees taken 8/26/2008. Both
images Nikon D SLR, 20-200mm lens, ISO 400 Details for#73:

An
unusual colourful sunset last weekend, caused by volcanic
dust of the Kasatochi in the atmosphere. Very fine yellow-purple
rays were visible high up in the sky. Difficult to catch
by camera, but a beautiful view. Nikon D300 with 12-24 mm
lens. |

In
reviewing my images from my recent flight from London to
Los Angeles, I realized that the high-altitude smog that
puzzled me on the flight must be vog from the eruption of
Kasatochi. The series of impressive sunsets here in southern
California this week reminded me about this image of the
vog. |
