"NGC 4523 is a Magellanic spiral galaxy located about 35 to 50 million light- years away in the constellation Coma Berenices. It was discovered by astronomer Heinrich d'Arrest on April 19, 1865. NGC 4523 is member of the Virgo Cluster. SN1999gq On December 23, 1999, a Type II supernova designated as SN1999gq was detected in NGC 4523. Distance estimates A distance of (13 ± 2 Mpc) for NGC 4523 was derived from using yellow supergiants in the galaxy as standard candles.

"The CTV-N-2 Gorgon IIC – also designated KGN, KUN, and CTV-2 – was an experimental drone, originally intended as a surface-to-surface missile, developed by the United States Navy near the end of World War II. It was used to test control and homing systems for guided missiles, and was also produced in small numbers as a target drone under the designations TD3N and KD2N. Design and development Late in World War II, the U.S. Navy began development of a pulsejet-powered bombardment missile,Ordway and Wakeford 1960, p.181. intended to be launched from ships for use against targets ashore; in April 1945, plans for the invasion of Japan called for the production of "several hundred" missiles, named Gorgon IIC; initially, 20 prototype missiles were to be produced by the Naval Aircraft Modification Unit in Pennsylvania, while an order for 100 was placed with the Singer Manufacturing Company, a sewing machine manufacturer, in August 1945.White 1991, p.36. The end of the war saw the cancellation of the production plans, however development continued, and in October 1945 the Gorgon IIC received the designation KGN-1.Parsch 2005 The Gorgon IIC was very similar in design to the Gorgon IIA air-to-air missile, being of canard configuration with a high- mounted monoplane wing and vertical and ventral stabilizing fins. The pulsejet, developed at the Naval Engineering Experiment Station, was in diameter and was mounted above the rear fuselage; launch was from the ground using a catapult or sled with a rocket booster, or from a carrier aircraft. In its original, bombardment configuration, the Gorgon IIC was intended to use active radar homing, similar to that used on the Bat guided bomb. Operational history Testing of the Gorgon IIC began in 1946; late that year it was redesignated KUN-1 to reflect its non-combat role, while in September 1947 it was redesignated CTV-2, and in 1948 received its definitive designation of CTV-N-2. Gorgon IIC was used to test guidance and control devices for guided missile development; in 1950, an active radar guidance system was trialled using a CTV-N-2, successfully homing from a distance of .Friedman 1982, p.201 Trials of the Gorgon IIC were considered generally satisfactory by the Navy. Eight target drone versions of the Gorgon IIC, originally designated TD3N-1 but, in March 1946, redesignated KD2N-1, were also produced; the KD2N was used in parachute-recovery trials around 1950.Ordway and Wakeford 1960, p.182. RTV-N-15 RTV-N-15 at the Udvar-Hazy Center The RTV-N-15 Pollux was derived from the Gorgon IIC airframe, the pulsejet engine being moved to an internal mounting, and it was intended to use a mixture of radar and infrared guidance. Pollux was first flown in 1948, however by 1951 it had been flown only three times, and the program was cancelled. Surviving aircraft A single example of the RTV-N-15 was donated by the U.S. Navy to the National Air and Space Museum in 1971; it is on display at the Steven F. Udvar-Hazy Center.
