The time of solar minimum is that of a star with a split personality.
Magnetic sun-spots from the old, dying cycle can overlap with new cycle
spots. The three groups in this image are all from old cycle number 23,
and will possibly be some of the last we will see - NASA scientists
predict the new cycle number 24 will begin to be felt before this year
is out. Photo details: Canon 350D, ISO 400 @ prime focus through an 80mm
Vixen refracting telescope, fitted with a solar filter, 1/1250th second
exposure. Image copyright to Graham Palmer. For more images, visit my

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. Anderson Night

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. Copyright (c) Dennis C. Anderson Night Trax

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. Anderson Night Trax

Wind and the Willow
Submitted by:
Dennis Anderson at Tue Apr 15 21:05:01 2008 UTC
Twelve-Mile Summit, in the White Mountains about 80 miles NE of
Fairbanks, can be a harsh place. The wind blows more than not and I have
turned back from this place several times due to blowing and drifting
snow. It is above the treeline and except for the tundra, there is
little vegetation here. These wind-shaped willows, photographed on March
29, 2008, were the only living thing around taller than a foot or so.
They had found refuge and a chance to start their slow, stunted growth
where a buldozed blade had cut a wayside at the summit. The wind was
pretty strong at sunset but had died down enough to leave the branches
still during this 30-second shot with the northern lights blazing
behind. Copyright (c) Dennis C. Anderson Night Trax Photography Contact

Ribbon of Delight
Submitted by:
Dennis Anderson at Tue Apr 8 20:20:01 2008 UTC
Time had been passing quickly on this March 27-28, 2008 night of auroral
activity and I really had completely lost track of it. But when I
started seeing tall rays of violet light in the northeast, I knew that
night would soon give in to dawn. It is the sun's direct light acting on
the aurora that can coax nitrogen molocules, high in the atmosphere, to
produce beautiful shades of blue and violet in a process known as
resonance scattering. This usually takes place during twilight hours
while the Earth is in the shadow of night but the aurora is reaching up
into sunlight at altitudes of up to 1000 km. (about 600 miles into
space). This is the highest type of aurora measured. I used a 6x7 cm.
medium format camera with a 38mm wide angle lens for this image along
the Chena River east of Fairbanks. Copyright (c) Dennis C. Anderson

Chasing Rabbits
Submitted by:
Dennis Anderson at Tue Apr 8 22:17:01 2008 UTC
Early on in our week-long aurora expedition, my brother had expressed
his desire to bag a snow-shoe hare for the stew pot. He had even
prepared a special sauce in anticipation. We saw many, many tracks day
after day but never had the opportunity to get one of these "waskwy
wabbits". Now, as if to tease us, here is a giant rabbit in the sky
leaping above the spruce along the Chena River on the early morning of
March 28, 2008. The sauce had frozen on the first night out and had
remained that way for the duration of the outing. Copyright (c) Dennis

Bright Band with Nitrogen Fringe
Submitted by:
Dennis Anderson at Tue Apr 8 17:55:01 2008 UTC
On the night of March 27-28 a diffuse band rapidly grows brighter and
begins to display color on its bottom edge. This is an indication that
higher energy particles are penetrating the atmosphere to lower levels
where nitrogen molocules are coaxed into producing reddish and purplish
emissions. The common green aurora is created by the excitation of
oxygen atoms at altitudes ranging from about 100 to 150 km. (60 to 90
miles). This colorful "nitrogen fringing" takes place as low as about
70km. (43 miles). This is as close to the ground as the aurora ever
gets. I used a 6x7 cm. medium format camera with a 75mm lens to record
the northwestern sky from the Chena River east of Fairbanks. Copyright

Bright Loop Dark Night

A bright loop appears over the spruce trees in the north bringing light

Shadows
Submitted by:
Dennis Anderson at Mon Apr 7 09:18:01 2008 UTC
As the camp fire was dying down the aurora began to intensify. It was
easily casting shadows on the snow during this moonless night of March
27-28, 2008 along the Chena River east of Fairbanks. This display became
so bright that I didn't even notice my headlamp was still on throwing
its red light onto the foreground. The sky became bright enough that
snipes had taken to the air with their strange whooing noises that they
make in flight, a ritual usually saved for the afternoon or evening
twilight. An owl hooted from a nearby tree. We sat in silence. Copyright

Elliptical halo 3-23-08
Submitted by:
Michael Ellestad at Sun Apr 6 15:30:01 2008 UTC
This is part of a series of photos I got a rare
elliptical halo display that lasted over two
hours in Ohio USA. Elliptical halos are a special
type of halo that forms in dissolving altocumulus
AC clouds rather than the cirrus clouds. This
started out as a single ellipse that lasted for
10 minutes then disappeared but then came back
much brighter and would have up to three ellipses
at one time. As the cloud would move the halo
would shrink expand.

Super double rainbow
Submitted by:
Michael Ellestad at Sun Apr 6 15:30:01 2008 UTC
This is another rainbow I got a month later and
this one is probably the best I have seen in
years not only was it very bright but the
secondary was bright and the primary showed at
least three interference supernummery bows. This
set of bows make some rainbows in past years I
have photographed look mediocre.

No Batteries Required
Submitted by:
Dennis Anderson at Sat Apr 5 19:08:01 2008 UTC
After several nights out, I noticed that the batteries on my (red)
headlamp were growing weak but I was prepared. I had stuffed extras into
one of my coat pockets just in case. It had been easy walking on the
frozen tundra and I had counted 300 steps out from camp as I didn't want
to loose my way in the dark. Then, it happened. The batteries in my
headlamp went completely dead. It was dark but I didn't panic. After
all, I had fresh batteries. So I spread the legs of my tripod and set my
camera down. Then I took a seat on the tundra and began to take my
headlamp apart carefully so as to not loose the parts in the dark. I
removed the three batteries and took mental note of their orientation so
that I could get the replacements back in the proper order. I then felt
in my pocket for the fresh batteries and that's when I had a moment of
realization: They were the wrong size! But wait, what is that bright
light shining behind me? I turned and saw the silent aurora gathering
strength to light up the night. It was very diffuse but had become super
bright and it was bathing all the snow and ice in its cool green light.
I didn't need the batteries after all! I could see perfectly well. This
image is taken during the bright display from Twelve-Mile Summit about
80 miles northeast of Fairbanks, Alaska on the early morning of March
28, 2008. Copyright (c) Dennis C. Anderson Night Trax Photography

Fisheye View of a Proton Arc
Submitted by:
Dennis Anderson at Thu Apr 3 23:01:01 2008 UTC
This shot was taken from the Denali Highway outside of Cantwell, Aalska
on March 25, 2008 using an all-sky circular fisheye lens. The camera is
pointed straight up and records everything from horizon to horizon.
North is at the bottom left while east is at bottom right. The Fuji
Velvia 100F film records a proton arc overhead vividly. Visually the
reddish color was just noticable in comparison to the green aurora seen
filling the northern horizon of the image. Copyright (c) Dennis C.

Hercules Rising
Submitted by:
Dennis Anderson at Thu Apr 3 20:13:01 2008 UTC
It had been a slow aurora season, between clouds and lack of activity
but I was determined to get some shots before the dark nights were
completely gone for the high north latitudes. This was the third night
out after a snow storm and clouds on the first two. Tonight we had found
ourselves under perfectly clear skies camped off the Denali Highway near
Cantwell, Alaska. There had been a little activity early on and a nice
proton arc to entertain but the aurora never arrived in full force.
Still, I had to get something and spent the entire night waiting fo my
chance. If this was to be the only shot I would still have been happy.

Under the Rainbow
Submitted by:
Dennis Anderson at Wed Apr 2 22:50:01 2008 UTC
The aurora was growing so intense that it was leaving shadows on the
snow during an outing on the Chena River east of Fairbanks, Alaska on
this night of March 26-27, 2008. It was impossible to hold still. There
were so many things going on in all parts of the sky at one time. This
arc in the northwest had suddenly brightened and formed many rays with
purplish undersides that indicated very energetic particles were now
penetrating the Earth's atmosphere to lower levels than the most common
green type of aurora. I used a 6x9 cm. medium format camera and a 50mm
wide-angle lens to record the spectacular sight above our campsite.

This image is taken with a 180-degree circular fisheye lens and is
looking roughly north from along the Chena River east of Fairbanks. It
spans from west to east and to overhead. The aurora gathered strength as
darkness set in on the night of March 26-27, 2008 but became rather
diffuse at times. Still, it was enough to light up the snow on this
moonless night. Copyright (c) Dennis C. Anderson Night Trax Photography

Pleasantly Surprised
Submitted by:
Dennis Anderson at Wed Apr 2 08:20:01 2008 UTC
Maybe its because the auroral activity has been slow this last year or
so or maybe its because I have too many cameras to keep track of or both
but I was finally able to finish a couple rolls of film that had been
kicking around for all of this last year and was pleasantly surprised to
find this image. It was taken on March 24, 2007 from the beach at Deep
Creek, Alaska along the frozen shore of Cook Inlet. The incredible
color comes from high energy particles striking nitrogen molocules lower
in the atmosphere than the green auroras. Copyright (c) Dennis C.
