Arne Henden

Henden moved to Ohio State University to work on the Large Binocular Telescope after gaining his doctorate. He also built several imagers and spectrographs for the 1.8-meter Perkins telescope.

in 1992, he returned to work at the United States Naval Observatory Flagstaff Station (NOFS) as a senior research scientist, the site where his love for astronomy first started. At NOFS, he specialized in visual and near-IR imaging systems and co-discovered 239046 Judysyd, a faint asteroid of the main-belt, in collaboration with astronomer Stephen Levine on 25 February 2006.^[3] Henden was also part of the team that created specifications for Lowell Observatory's 4.3-m Discovery Channel Telescope. He has also worked on the Sloan Digital Sky Survey and consulted for the Radio Astronomy Institute in developing a robotic observatory near the Grand Canyon.

In the Spring of 2004, Henden was named director of the American Association of Variable Star Observers (AAVSO), an organization he had long been a member of.

Henden has authored more than 100 articles in peer-reviewed publications as either primary or co-author. Henden has also positioned himself as a specialist in photometry by writing one of the classic texts in the subject: Astronomical Photometry (1978: Willman-Bell) Henden has worked extensively with amateurs interested in variable stars and minor planet astrometry mainly through the AAVSO.

He was elected a Legacy Fellow of the American Astronomical Society in 2020.^[4]

33529 Henden, a main-belt asteroid discovered by American amateur astronomer Charles Juels in 1999, was officially named in his honor by IAU's Minor Planet Center on 18 September 2005 (M.P.C. 54827).^[2][5]
