Sun Dog Over Redoubt Volcano

Submitted by: Dennis Anderson at Wed Jul 15 20:09:01 2009 UTC

A rainbow-hued sundog, or parihelion, is visible over redoubt Volcano as viewed from near Homer, Alaska on the afternoon of July 14, 2009. Sunlight refracting and reflecting through ice crystals high in the atmosphere cause the effect. Sundogs often come in pairs located 22 degrees to either side of the sun while it is low in the afternoon or morning sky. Copyright (c) Dennis C.

Volcano and Aurora

Submitted by: Dennis Anderson at Sat Apr 25 20:40:01 2009 UTC

On the early morning of March 21, 2009, Redoubt Volcano (bottom left) was just starting to wake up from its 20-year slumber when I took this shot of the aurora borealis putting on its own little show. The view is looking northwest from Alaska's Kenai Peninsula. I used Fuji Z800 film in a 6x9 cm. medium- format camera with a 98mm f1.4 lens for this 8-second exposure. Copyright (c) Dennis C.

Volcanic Sunset April 20, 2009

Submitted by: Dennis Anderson at Thu Apr 23 20:05:01 2009 UTC

A sulphur-rich gas plume is seen drifting southward from Redoubt Volcano during its current phase of activity as seen from near Homer, Alaska. Its "sister" volcano Illiamna is at the recieving end of the plume and is back-lit by the recently set sun. The plume, rich in sulphur dioxide, was detected by satellite extending to another 600 miles downstream. Copyright (c) Dennis C.

Volcano Sunset April 4, 2009

Submitted by: Dennis Anderson at Tue Apr 7 00:20:01 2009 UTC

This morning we awoke to the rumble of thunder during a major eruption of Redoubt Volcano. The day turned to night as the ash cloud made a direct path to the southern Kenai Peninsula. Later, after the ash cloud had passed high winds began to pick the ash up and blow it out of the trees in what locals are refuuring to as "the ash storm". It wasn't until evening that the skies began to clear and it gave us our first glimpse of the restless mountain. This image is taken after sunset and shows the steam/ash plume traveling southward from Redoubt on the right over its sister volcano, Illiamna, at left. This view is looking northwest from near Homer, Alaska. Copyright (c) Dennis C. Anderson Night Trax Photography Contact at: auroradude@acsalaska.net or visit: www.auroradude.com

Redoubt Mushroom Cloud

Submitted by: Dennis Anderson at Sat Mar 28 04:15:01 2009 UTC

Redoubt has been evry active indeed today. This is the fourth eruption so far. This one started at 7:25p.m. ADT March 27, 2009. This image is taken about ten minutes into the event. A mushroom cloud to about 40,000 feet is visible above the low clouds that obscure the summit. High clouds and lingering ash/haze also oscure the view of the cloud somewhat. The height of the cloud later reached about 55,000 feet. Copyright (c) Dennis C. Anderson Night Trax Photogrphy contact at auroradude@acsalaska.net or visit www.auroradude.com

Redoubt Ash/Steam cloud to 65,000 feet

Submitted by: Dennis Anderson at Thu Mar 26 18:56:01 2009 UTC

This morning of March 26,2009 saw another explosive eruption of 10,200 foot redoubt volcano sending ash and steam to over 65,000 feet. While the volcano is not visible due to clouds and ash obscuring the peak I have marked its approximate location with a red "RS" at the bottom left of the image. Copyright (c) Dennis C.

Redoubt Steam Plume

Submitted by: Dennis Anderson at Sun Mar 15 23:15:01 2009 UTC

This afternoon I noticed a steam plume rising above the summit of Redoubt Volcano from our home near Homer, Alaska. Seismicity has increased again and it looks like it really could go off.

Moonset Over Illiamna Volcano

Submitted by: Dennis Anderson at Mon Feb 9 21:24:01 2009 UTC

A long and bright night comes to an end as the full moon sets behind Illiamna Volcano. Steam can be seen rising from a fumerole near the summit as the moon begins to set behind the "South Twin". Interestingly I witness a large avalanche at the dark spot to the left of the peak just after the sun rose on the mountain. There is never a dull moment in this dynamic environment. I took this shot from our perch near Homer, Alaska on February 9, 2009. Copyright (c) Dennis C. Anderson Night Trax Photography Contact at: auroradude@acsalaska.net or visit www.auroradude.com

Redoubt Volcano

Submitted by: Dennis Anderson at Thu Jan 29 21:56:01 2009 UTC

10,000 foot Redoubt volcano is the northernmost peak in Alaska's Aleutian Range and is an active strato-volcano. In recent days it is showing signs of another eruption having produced the last in 1989-90. This view is looking northwest from Diamond Ridge near Homer. I can only hope for a nice clear day, like this one in January of 2006, when it decides to blow again. Copyright (c) Dennis C.

"Fata Morganna"

Submitted by: Dennis Anderson at Sat Jan 24 19:59:01 2009 UTC

Warm air was over riding cold air creating this nice example of fata morganna which is an atmospheric phenomenon similar to mirage. The effect is created during temperature inversions when warm air overlies cold dense air at the surface. The different densities of the air masses causes refraction in the atmosphere that can make distant objects appear above a horizon where they are not normally visible or streach objects into impossible shapes. Mountains might look taller and may even seem to appear where there are none in actuallity. This example is looking northwards towards the Alaska Range about 70-80 miles distant and is taken from the Homer area on January 22, 2009 Copyright (c) Dennis C.

Animated Green Flash

Submitted by: Dennis Anderson at Wed Dec 31 00:29:01 2008 UTC

The sun was at its furthest point south on December 21st 2008 and as luck would have it we were able to catch a rare green flash from our perch near Homer, Alaska as it set over the Gulf of Alaska on the North Pacific Ocean. This is an animation of the setting sun taken from 20 frames separated by about 30 seconds. The last few frames are spaced just as close as the digital camera was able to record the event.

"Shadow of a Mountain"

Submitted by: Dennis Anderson at Sun Dec 21 23:38:01 2008 UTC

While looking through my image files I ran across this jewel I had overlooked before. This image was acquired on March 24, 2007 from the beach at Deep Creek, Alaska on the Kenai Peninsula. The beach, along the eastern shore of Cook Inlet, is littered with ice that has been washed up and glazed by the waves and tides during a long spell of unseasonably cold temperatures. Across the Inlet 10,197 foot Redoubt Volcano is visible at left.The aurora borealis twists and curls into spiral formations to the right of the volcano and is then reflected in the waters of the inlet. Further to the right, a void in the aurora creates the effect of a shadow cast into the night sky by the cone-shaped volcano. Nitrogen fringing is visible as reddish emissions in the bands of aurora at right as particularly powerful particles penetrate the Earth's atmosphere to altitudes down to 35-40 miles high as opposed to the common green oxygen emissions that take place between about 50 and 100 miles altitude. These types of emissions by molecular nitrogen are as close to the ground as the aurora ever gets. A bright moon is seen at the left and reflected in the water. Moonlight sparkles off the icy beach in the foreground. I used a custom-built 6x9cm. medium-format camera and Kodak E100VS film for the origional image. COPYRIGHT (C) Dennis C.

Early Comes the Day

Submitted by: Dennis Anderson at Fri Apr 25 20:03:01 2008 UTC

The early light of a new dawn grows stronger while the aurora fades into memory as seen from our Twelve-Mile Summit camp March 29, 2008 about 80 miles northeast of Fairbanks. I retired to my sleeping bag for a few short hours and woke to a blazing sun. Our little windbreak had turned into a great reflector and over our morning coffee we soon realized that we would surely fry in the intensified sunlight if we stayed too long. It was time to go so after packing our strung-out gear we started our three-day journey back to Homer. Copyright (c) Dennis C.

Short Break

Submitted by: Dennis Anderson at Fri Apr 25 19:41:01 2008 UTC

Since I was up all night and mostly on my feet, I decided to take a short break and if you look closely, you will see my ghosted image sitting on the cooler at right for part of this exposure. At first, I thought it was the aurora gathering for another wave of activity but soon enough I realized it was the light of the dawn approaching at our camp on Twelve-Mile Summit.

Wood is Good

Submitted by: Dennis Anderson at Tue Apr 15 21:46:01 2008 UTC

Wind was a definate a factor while camping on this March 28, 2008 evening at Twelve-Mile Summit. We took advantage of a snow berm and readily availible blocks of snow to construct a crude shelter. Luckily, one of us was smart enough to include a large bow saw and axe in our gear so we stopped every day, while traveling, to replenish our supply of wood. It was a good thing too because there was no wood to be had up here above the tree line. Copyright (c) Dennis C.
