Lambert died on 6 September 1928 of heart disease. Don Walko  Don Walko (born February 24, 1953) was a Democratic member of the Pennsylvania House of Representatives for the 20th District. Walko was elected in 1994 and was in office until 2010. He resigned on January 3 after being elected a judge for the 5th District of the Allegheny County Court Common Pleas.   1625 The NORC  1625 The NORC, provisional designation , is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 55 kilometers in diameter. It was discovered on 1 September 1953, by Belgian astronomer Sylvain Arend at the Royal Observatory of Belgium in Uccle, Belgium. It was named after the IBM Naval Ordnance Research Calculator (NORC). "The NORC" orbits the Sun in the outer main-belt at a distance of 2.5–3.9 AU once every 5 years and 8 months (2,083 days). Its orbit has an eccentricity of 0.23 and an inclination of 16° with respect to the ecliptic. The asteroid was first identified as at Heidelberg Observatory in 1914. Its observation arc begins 24 years prior to its official discovery observation, when it was identified as at Uccle. In the Tholen classification, "The NORC" is a common carbonaceous C-type asteroid. Between 2009 and 2014, five rotational light-curve were obtained of "The NORC" from photometric observations taken by René Roy, David Higgins and the Palomar Transient Factory. The light-curves gave a rotation period between 12.94 and 18.820 hours with a change in brightness of 0.06 to 0.33 in magnitude (). The best rated result with a period of 13.959 hours (Δmag 0.16) was obtained by Australian amateur astronomer David Higgins. According to the surveys carried out by Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "The NORC" measures between 44.66 and 75.11 kilometers in diameter, and its surface has an albedo of 0.023 and 0.065. The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 47.60 kilometers using an absolute magnitude of 10.34. This minor planet was named after the IBM Naval Ordnance Research Calculator (NORC), IBM's first-generation vacuum tube computer built in the 1950s "(also see List of vacuum tube computers and )".
