S62 on a 9.9 yr Orbit around SgrA*
  We observe the S-cluster star S62 on its Keplerian orbit around the
supermassive black hole in the center of our galaxy, SgrA*. The orbital time
period of S62 around SgrA* is 9.9 years. We derive its mass to be around 2
M_solar which is consistent with other members of the S-cluster. From the
Lucy-Richardson deconvolved images, we determine a K-band magnitude of 16.1
mag. We observe almost two complete orbits of the star with two different and
independent telescopes and three different instruments. The close distance of
S62 to SgrA* at its periapse of around 2 mas results in a gravitational
periapse shift of almost 10%/orbit.
