Question: What is the official IAU name for the main star that is ioninizing the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

question:
Question: Who was the leader of the Porte in 1912? Passage:The modern Albanian-Serbian conflict has its roots in the expulsion of the Albanians in 1877-1878 from areas that became incorporated into the Principality of Serbia. Prior to the outbreak of the First Balkan War, the Albanian nation was fighting for a national state. At the end of 1912, the Porte recognised the autonomy of Albanian vilayet. These events for Albanian autonomy and Ottoman weakness were viewed at the time as directly threatening the Christian population of the region with extermination. The Balkan League (comprising Serbia, Montenegro, Greece and Bulgaria) jointly attacked the Ottoman Empire and during the next few months partitioned all Ottoman territory inhabited by Albanians. The Kingdom of Serbia and the Kingdom of Greece occupied most of the land of what is today Albania and other lands inhabited by Albanians on the Adriatic coast. Montenegro occupied a part of today's northern Albania around Shkoder. The Serbian army in the region viewed its role as protecting local Orthodox Christian communities and avenging the medieval battle of Kosovo, though it forced Catholic Albanians to convert to Orthodox Christianity.

Question: Were there any casualties from the collision between the USNS Asterion and the MV Kokoku? Passage:After her acquisition by the U.S. Coast Guard she was converted for use as a buoy tender at the Bethlehem Shipyard in San Francisco. She was commissioned USCGC Magnolia (WAGL-328) on 19October 1947. She was first assigned to U.S. Coast Guard Base Yerba Buena Island, San Francisco. Her primary duties there were aids to navigation (ATON), servicing light stations and lightships on the California coast, search and rescue, and law enforcement. From 28 to 29 April 1951 she assisted the Japanese MVFlyer. On 9February 1960 she assisted the disabled MVAngelo Petri two miles south of the San Francisco Bar. On 5June 1963 she assisted following the collision between the U.S. Navy Military Sea Transportation Service (MSTS) ship USNS Asterion (T-AF-63) and the Japanese merchantman MVKokoku Maru and transported 19 crew members from the Japanese ship to SanFrancisco. From 21 to 24 June 1965 she escorted the damaged catamaran SVJudyAl 165miles southwest of Eureka, California to that port as her hull was too damaged to permit towing. She then transferred to U.S. Coast Guard Base Tongue Point, Astoria, Oregon on 1September 1965, and redesignated WLB-328. Her primary duties there were aids to navigation (ATON), search and rescue, and law enforcement. She also tended the Columbia River Lightship on the Columbia River Bar. On 6December 1967 she escorted the distressed MVDavid E. Day, which had grounded on the Columbia River Bar. On 10August 1968 she assisted following the collision between MVSeatrain Washington and SSRoseS 17miles east of Cape Flattery, Washington in heavy fog. Magnolia was decommissioned on 13August 1971. She was stored at U.S. Coast Guard Training Center (TRACEN) at Government Island, Alameda, California until sold.
