Triangulum Australe

Triangulum Australe is a small constellation in the far Southern Celestial Hemisphere. Its name is Latin for "the southern triangle", which distinguishes it from Triangulum in the northern sky and is derived from the equilateral pattern of its three brightest stars, it was first depicted on a celestial globe as Triangulus Antarcticus by Petrus Plancius in 1589, with more accuracy and its current name by Johann Bayer in his 1603 Uranometria. The French explorer and astronomer Nicolas Louis de Lacaille charted and gave the brighter stars their Bayer designations in 1756. Alpha Trianguli Australis, known as Atria, is a second-magnitude orange giant and the brightest star in the constellation, as well as the 42nd-brightest star in the night sky. Completing the triangle are the two white main sequence stars Beta and Gamma Trianguli Australis. Although the constellation lies in the Milky Way and contains many stars, deep-sky objects are not prominent. Notable features include the open cluster NGC 6025 and planetary nebula NGC 5979.

Italian navigator Amerigo Vespucci explored the New World at the beginning of the 16th century. He learnt to recognize the stars in the southern hemisphere and made a catalogue for his patron king Manuel I of Portugal, now lost; as well as the catalogue, Vespucci wrote descriptions of the southern stars, including a triangle which may be either Triangulum Australe or Apus. This was sent to his patron in Florence, Lorenzo di Pierfrancesco de' Medici, published as Mundus Novus in 1504; the first depiction of the constellation was provided in 1589 by Flemish astronomer and clergyman Petrus Plancius on a ​32 1⁄2-cm diameter celestial globe published in Amsterdam by Dutch cartographer Jacob Floris van Langren, where it was called Triangulus Antarcticus and incorrectly portrayed to the south of Argo Navis. His student Petrus Keyzer, along with Dutch explorer Frederick de Houtman, coined the name Den Zuyden Trianghel. Triangulum Australe was more depicted in Johann Bayer's celestial atlas Uranometria in 1603, where it was given its current name.

Nicolas Louis de Lacaille portrayed the constellations of Norma and Triangulum Australe as a set square and ruler, a compass, a surveyor's level in a set of draughtsman's instruments in his 1756 map of the southern stars. Depicting it as a surveyor's level, German Johann Bode gave it the alternate name of Libella in his Uranographia. German poet and author Philippus Caesius saw the three main stars as representing the Three Patriarchs, Abraham and Jacob; the Wardaman people of the Northern Territory in Australia perceived the stars of Triangulum Australe as the tail of the Rainbow Serpent, which stretched out from near Crux across to Scorpius. Overhead in October, the Rainbow Serpent "gives Lightning a nudge" to bring on the wet season rains in November. Triangulum Australe is a small constellation bordered by Norma to the north, Circinus to the west, Apus to the south and Ara to the east, it lies with only Circinus in between. The constellation is located within the Milky Way, hence has many stars.

A equilateral triangle, it is identifiable. Triangulum Australe lies too far south in the celestial southern hemisphere to be visible from Europe, yet is circumpolar from most of the southern hemisphere; the three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is "TrA". The official constellation boundaries, as set by Eugène Delporte in 1930, are defined by a polygon of 18 segments. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 14h 56.4m and 17h 13.5m, while the declination coordinates are between −60.26° and −70.51°. Triangulum Australe culminates each year at 9 p.m. on 23 August. In defining the constellation, Lacaille gave twelve stars Bayer designations of Alpha through to Lambda, with two close stars called Eta, while Lambda was dropped due to its dimness; the three brightest stars, Alpha and Gamma, make up the triangle. Identified by its orange hue, Alpha Trianguli Australis is a bright giant star of spectral type K2 IIb-IIIa with an apparent magnitude of +1.91, the 42nd-brightest star in the night sky.

It lies 424 light-years away and has an absolute magnitude of −3.68 and is 5,500 times more luminous than our Sun. With a diameter 130 times that of our Sun, it would reach the orbit of Venus if placed at the centre of the Solar System; the proper name Atria is a contraction of its Bayer designation. Beta Trianguli Australis is a double star, the primary being a F-type main-sequence star with a stellar classification of F1V, an apparent magnitude of 2.85. Lying only 40 light-years away, it has an absolute magnitude of 2.38. Its companion 3 arcminutes away, is a 13th-magnitude star which may or may not be in orbit around Beta; the remaining member of the triangle is Gamma Trianguli Australis with an apparent magnitude of 2.87. It is an A-type main sequence star of spectral class A1 V. Located outside the triangle near Beta, Delta Trianguli Australis is the fourth-brightest star at apparent magnitude +3.8. It lies 606 light-years away. A binary star, it has a 12th-magnitude companion star separated by 30 arcseconds from the primary.

Lying halfway between Beta and Gamma, Epsilon Trianguli Australis is an optical double. The brighter star, Epsilon Trianguli Australis A, is an orange K-type sub-giant of spectral type K1.5III with an apparent magnitude of +4.11. The optical companion, Epsilon Trianguli Australis B, is

Abruka

Abruka is an 8.78 km² Estonian island in the Gulf of Riga, 4 km south of the island of Saaremaa. Together with few neighbouring smaller islands Abruka forms the village of Abruka, part of Saaremaa Parish, Saare County; the village has a population of 33 and an area of 10.1 km². The first records about the population on Abruka originate from the Middle Ages, when the Bishop of Ösel-Wiek founded a horse breeding manor there. Permanent population developed in the 18th century. 1881–1972 an elementary school operated on Abruka. Abruka is the site of a Central European-type broadleaf forest, rare in the region. To protect this a nature reserve was created in 1937. There's a library and a museum, located on the side of the former manor park in the oldest building on Abruka. Abruka can be reached by postboat Heili from Roomassaare harbour in Kuressaare; the twin writers Jüri Tuulik and Ülo Tuulik were born on Abruka. Kasselaid www.abruka.ee Abruka.pri.ee

German submarine U-662

German submarine U-662 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 7 May 1941 by Deutsche Werft, Hamburg as yard number 811, launched on 22 January 1942 and commissioned on 9 April 1942 under Korvettenkapitän Wolfgang Hermann. German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-662 had a displacement of 769 tonnes when at the 871 tonnes while submerged, she had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of 750 metric horsepower for use while submerged, she had two 1.23 m propellers. The boat was capable of operating at depths of up to 230 metres; the submarine had a maximum submerged speed of 7.6 knots.

When submerged, the boat could operate for 80 nautical miles at 4 knots. U-662 was fitted with five 53.3 cm torpedo tubes, fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, a 2 cm C/30 anti-aircraft gun. The boat had a complement of between sixty; the boat's career began with training at 5th U-boat Flotilla on 9 April 1942, followed by active service on 1 October 1942 as part of the 7th Flotilla for the remainder of her service. In 4 patrols she sank 3 merchant ships, for a total of 18,609 gross register tons and damaged one merchant ship. U-662 took part in eleven wolfpacks, namely Panther Leopard Südwärts Delphin Spitz Jaguar Without name Adler Meise Specht Fink On the night on 26 December 1942 U-662 reported sighting Convoy ONS 154. U-662 sunk the crippled and straggling Ville de Rouen, attacked earlier by U-225. On 19 July a US Liberator bomber dropped four depth charges, but broke off the attack after sustaining flak damage. U-662 escaped undamaged; the next day, U-662 was again attacked by US aircraft, this time a Douglas B-18 Bolo aircraft, but again she escaped undamaged.

She was sunk the following day. U-662 was sunk on 21 July 1943 in the North Atlantic in position 03°56′N 48°46′W, by depth charges from US Catalina from Patrol Squadron VP-94. Apart from the commander and two other crew members, all hands were lost. Oberleutnant zur See Heinz-Eberhard Müller was so injured that he was repatriated to Germany in March 1944 as he was no longer fit for combat. Helgason, Guðmundur. "The Type VIIC boat U-662".

Mountains (Lonestar song)

"Mountains" is a song written by Richie McDonald, Larry Boone and Paul Nelson, recorded by American country music band Lonestar. It was released in June 2006 as the lead-off single from their seventh studio album of the same name; the song is the band's final Top Ten hit, reaching a peak of number 10 on the U. S. country singles charts in late 2006. "Mountains" is a mid-tempo in which the narrator cites two examples of people who overcome difficult situations in their lives. The first is a single mother who has to work two jobs to put her kids through school, the second is a armed service veteran who sustained an injury in combat that required him to have a leg amputated, but runs a marathon wearing a prosthesis despite the pain he feels. In both situations, the narrator uses mountains; the music video was filmed west of Denver and was directed by Kristin Barlowe. Lyrics of this song at MetroLyrics
