'''1632 Sieböhme''', provisional designation 1941 DF, is a stony [[asteroid]] and slow rotator from the middle region of the [[asteroid belt]], about 27 kilometers in diameter. It was discovered by German astronomer [[Karl Reinmuth]] at [[Heidelberg-Königstuhl State Observatory|Heidelberg Observatory]] on 26 February 1941.<ref name="MPC-Siebohme" />

The asteroid orbits the Sun at a distance of 2.3–3.0&nbsp;[[Astronomical unit|AU]] once every 4 years and 4 months (1,580 days). Its orbit shows an [[orbital eccentricity|eccentricity]] of 0.14 and is [[orbital inclination|tilted]] by 6 degrees to the plane of the [[ecliptic]]. [[Light-curve]] observations measured a long [[rotation period]] of more than 56 hours.<ref name="geneva-obs" /><ref name="Carbognani-2014a" /><ref name="Waszczak-2015" /> For a stony [[S-type asteroid|S-type]] asteroid, it has a exceptionally low [[geometric albedo]] of around 0.07, according to observations carried out by the [[Wide-field Infrared Survey Explorer|WISE]] and [[NEOWISE]] missions.<ref name="Masiero-2012" /><ref name="WISE" />

The minor planet was named in honor of German astronomer Siegfried Böhme (1909–1996), staff member at [[Astronomisches Rechen-Institut]] in Heidelberg since 1949. He improved upon the [[orbital elements]] of many asteroids, in particular upon [[919 Ilsebill]].<ref name="springer" />

1632 Sieböhme, provisional designation 1941 DF, is a stony asteroid and slow rotator from the middle region of the asteroid belt, about 27 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 26 February 1941.[9]

The asteroid orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,580 days). Its orbit shows an eccentricity of 0.14 and is tilted by 6 degrees to the plane of the ecliptic. Light-curve observations measured a long rotation period of more than 56 hours.[6][7][8] For a stony S-type asteroid, it has a exceptionally low geometric albedo of around 0.07, according to observations carried out by the WISE and NEOWISE missions.[4][5]

The minor planet was named in honor of German astronomer Siegfried Böhme (1909–1996), staff member at Astronomisches Rechen-Institut in Heidelberg since 1949. He improved upon the orbital elements of many asteroids, in particular upon 919 Ilsebill.[2]
