Nh (digraph)

Nh is a digraph of the Latin alphabet, a combination of N and H. Together with lh and the interpunct, it is a typical feature of Occitan, a language illustrated by medieval troubadours.

African languages

In some African languages, nh, such as Gogo, it's a voiceless /n̥/.

In the pre-1985 orthography of Guinea for its languages, nh represented a velar [ŋ], which is currently written ŋ.

Asian languages

In the Gwoyeu Romatzyh romanization of Mandarin Chinese, initial nh- indicates an even tone on a syllable beginning in [n], which is otherwise spelled n-.

Japanese

Early romanizations of Japanese, influenced by Portuguese orthography, sometimes used nh to represent a prepalatal. Today, this is usually written ny.

Vietnamese

In Vietnamese, nh represents a palatal [ɲ] word-initially. It was formerly considered a distinct letter, but is no longer. When this digraph occurs word-finally, its phonetic value varies between dialects:

9963 Sandage

9963 Sandage, provisional designation 1992 AN, is a stony asteroid from the inner regions of the asteroid belt, about 5.5 kilometers in diameter. It was discovered by American female astronomer Eleanor Helin at the U.S. Palomar Observatory in California on 9 January 1992.

The stony S-type asteroid is a member of the Phocaea family, a group of asteroids with similar orbital characteristics. It orbits the Sun at a distance of 1.7–3.0 AU once every 3 years and 7 months (1,308 days). Its orbit shows an eccentricity of 0.28 and an inclination of 23 degrees from the plane of the ecliptic.

In 2012 and 2015, two photometric light-curve analysis at the Palomar Transient Factory and at Texas Tech's Preston Gott Observatory rendered a well-defined rotation period of 4.65 hours with a high brightness amplitude of 0.56 and 0.43 in magnitude, respectively. The Collaborative Asteroid Lightcurve Link assumes an albedo 0.23, which is a typical value for the surface of stony asteroids, and calculates a diameter of 5.45 kilometers based on an absolute magnitude of 13.53.
