From September 2015 until August 2017, the Advanced LIGO and Virgo gravitational-wave detectors conducted their first two observing runs O1 and O2. Since the milestone detection of gravitational waves from two coalescing black holes, GW150914, a further nine binary black holes collisions as well as one binary neutron star inspiral have been identified, firmly establishing the field of gravitational-wave astronomy. After a commissioning break, the third observing run commenced on April 1, 2019 which has since seen the public announcement of several tens of gravitational-wave candidate events. In this proceedings, we summarise the observations during O1 and O2 and briefly discuss the current status.
