The 41st RING OF FIRE EXPEDITIONS annular solar eclipse venture successfully viewed and photographed the annular eclipse of the Sun on May 10, 2013 from the atoll of Tarawa in the Republic of Kiribati.

At central eclipse time Lynn Palmer photographed the eclipse projected onto a shirt as the Sun’s image was projected through a hole in a thatched room at the Kiribati parliament complex. However, it is important to mention that on eclipse morning we experienced two downpours at our hotel, FEMA Lodge which did not portend well for the coming morning.
Eclipse morning dawned with many clouds over the hotel.
Above you can see a combination of a tree leaf shape which can produce certain crescents. Depending on the leaf shapes and distances as well as wind speeds the crescents can be clear or ambiguous at best . P.Maley photo.

Not to be deterred by morning cloud, myself and Lynn headed 3 km east and set up at the Kiribati Parliament building, the only private area we could find. The rest of our 10 member team set up at FEMA Lodge during the very lengthy 4 hour long eclipse interval. It should be noted that when we arrived in Tarawa and asked the purpose of our visit, we stated ‘for the solar eclipse’. Nobody knew about the eclipse which was to occur the following day!

Clouds persisted in front of the Sun until shortly after 1st contact.
The sky was covered until shortly before 2nd contact. When things look this bad, you generally have lots of time to snap such images. P.Maley photo.
I took this shot with a Nikon D3100, at ASA 400, 1/4000 through a Takahashi FC-60 with a focal length of 380mm. Initially the f/5.9 focal ratio showed very bright images, so I resorted to a technique to reduce the aperture by placing a card in front of the solar filter at 50%, 75% and 90% blockages. During the annular phase we did hear roosters crowing.
Blocking mask created from a tour brochure and operated by Lynn Palmer. This proved most useful prior to the start of annularity. The mask actually blocked too much light even at 50% at that time.

Setup at any eclipse is important. For Tarawa, the floor was hot concrete and a stable lawn sprinkler tripod served as the base. My Takahashi FC-60 with Nikon D3100 attached (f/5.9) generated a relatively wide field, mainly beneficial for total eclipses. A right angle viewer borrowed for the occasion was vital in being able not only to avoid looking straight up (73 degree elevation at central eclipse time) but permitted relatively easy focusing with both a 1x and 2x diopter. The mount was an Orion EQ-1 with slow motion knobs in RA and Dec used to conduct manual tracking.
At first I used a towel as a buffer between me and the concrete but later a small box served the purpose much better. Notice the Fiji bottled water used as a counterweight. A visor worked to shield theSun partly and when turned backward it was simpler to focus.

Byron Braswell determined from his GPS-based camera and resulting images that 2nd contact occurred at 12.1150 and third contact at 12.17.45 yielding 5m55s of annularity compared to 5m59s predicted. Coordinates of the observing site at FEMA Lodge were 1 deg 20m 25.6 s North, 173 deg 01m 32.0 s East.

TARAWA AND SOLOMON ISLANDS BATTLEFIELDS
Guadalcanal is the location of one of the more famous World War II battles where the US military reportedly handed the Japanese their first defeat in more than 1,000 years.

Map of areas in the Solomons were some famous battles took place. These include Savo Island where the US suffered a significant defeat at the hands of the Japanese navy. Significant battle areas included Tulagi, Lunga Point, Tenaru, Mount Austen (see the TV movie “The Pacific”), Matanikau River, bloody Ridge, Galloping Horse, Gavutu and others.

The Battle of the Tenaru, sometimes called the Battle of the Ilu River or the Battle of Alligator Creek, was a land battle between the Imperial Japanese Army and Allied ground forces (mainly of the US Marine Corps) that took place on August 21, 1942 on the island of Guadalcanal during the Pacific campaign of World War II. The battle was the first major Japanese land offensive during the Guadalcanal campaign.
In the battle, U.S. Marines, under the overall command of U.S. Major Gen. Alexander Vandegrift , repulsed an assault by the “First Element” of the “Ichiki” Regiment, under the command of Japanese Colonel Kiyonao Ichiki. The Marines were defending the Lunga perimeter, which guarded Henderson Field, which was captured by the Allies in landings on Guadalcanal on August 7. Ichiki’s unit was sent to Guadalcanal in response to the Allied landings with the mission of recapturing the airfield and driving the Allied forces off the island.
Underestimating the strength of Allied forces on Guadalcanal, which at that time numbered about 11,000 personnel, Ichiki’s unit conducted a nighttime frontal assault on Marine positions at Alligator Creek on the east side of the Lunga perimeter. Ichiki’s assault was defeated with heavy losses for the Imperial attackers. The Marine units counterattacked Ichiki’s surviving troops after daybreak, killing many more of them. All but 128 of the original 917 of the Ichiki Regiment’s First Element were killed in the battle.
