Context. The sungrazer comet C/2012 S1 (ISON) (perihelion at rh = 0.0125 AU from the Sun) was bright and active when discovered in September 2012 at 6.3 AU from the Sun. Aims. Our goal was to characterize the distant gaseous and dust activity of this comet, inbound, from observations of H2O, CO and the dust coma in the far-infrared and submillimeter domains. Methods. We report observations undertaken with the Herschel space observatory on 8 and 13 March 2013 (rh = 4.54–4.47AU) and with the 30 m telescope of Institut de Radioastronomie Millimétrique (IRAM) in March and April 2013 (rh = 4.45–4.18 AU). The HIFI instrument aboard Herschel was used to observe the H2O 110 − 101 line at 557 GHz, whereas images of the dust coma at 7...
