  The German-British laser-interferometric gravitational wave detector GEO 600
is in its 13th year of operation since its first lock in 2001. After
participating in science runs with other first generation detectors, GEO\,600
has continued collecting data as an astrowatch instrument with a duty cycle of
62% during the time when the other detectors have gone offline to undergo
substantial upgrades. Less invasive upgrades to demonstrate advanced
technologies and improve the GEO 600 sensitivity at high frequencies as part of
the GEO-HF program have additionally been carried out in parallel to data
taking. We report briefly on the status of GEO 600.
