Summary:
On June 12, 2009, Russia's Sarychev Peak volcano erupted, hurling
an enormous plume of ash and sulfur dioxide into the stratosphere.
This has produced some unusually beautiful sunrises and sunsets
around the northern hemisphere. When the sun goes down, delicate
ripples
of white appear over the western horizon. Then, as twilight
deepens, the sky turns a lovely shade of "volcanic lavender."
Fine
volcanic aerosols in the stratosphere scatter blue light which,
when mixed with ordinary sunset red, produce the lavender hue.
Other signs to look for include a bright yellow "twilight
arch" and long crepuscular rays and shadows.

The volcanic
sky show continues over Poland. During the past several
days, the sunsets and sunrises have become more dramatic.
Today morning, about 30-40 minutes before sunrise this display
of long crepuscular rays and shadows appeared in the east
with great contrast and color. Thise images respresent my
visual impression pretty good. It was wonderful and fantastic!

Having
read about the Sarychev Peak volcanic sunsets on Spaceweather,
we knew there was the chance of something being up. About
two hours before sunset on Friday 3rd July 2009 at our location
in Chelmsford UK, we noticed a layer of white 'stranded'
or 'combed' cloud in the western sky. The strands were too
linear to be cirrus and, were just like those shown in the
Sarychev Peak gallery. So we kept on watching. Here is the
result. It was not quite a liliac sky, but maybe tonight.
Another observer some 200 miles to the west of our location
in Lancashire also witnessed the same phenomina, so the
cloud must have been well distributed across England. Happy
sunset watching :-) |

The
volcanic clouds were reminiscient of NLCs except that you
could see them well before sunset and only a short while
after. I couldnt discern any movement as the contrast between
the sky background and the clouds was rather low. Camera
was Sigma Dp1 1/8s f11 ISO50 |

An
after before the sun set tonight clouds from the Sarychev
Peak volcano began to appear in the west looking very much
like Noctilucent clouds in recent weeks. They lasted until
an hour after sunset. Camera, Pentax Ist Dl 18mm lens. |

Beautiful
sunset, displaying some strange and wonderful structure.
I have heard about these volcanic sunsets from around the
world recently but had no idea what to expect. The streamers
and waves stretching across the evening sky were quite stunning
and lasted some time into the deep twilight. As the display
was fading a small patch of NLC began to shine through in
the north western portion of the sky which complemented
the dimming sunset colours. I have stitched together two
panoramic images of the early part of the display and toward
the end as the sky turned toward a lovely purple hue. There
is a portrait style image that I have stretched the contrast
on slightly to reveal both the NLC and some broad but very
subtle volcanic waves above the NLC display. Photo details
- Canon EOS 40D, ISO 200 with a 17-44mm f4 lens set at f9
1/40 second for the sunset images and f7 15 seconds for
the NLC/ volcanic waves images. |
