In February 2012 the collaboration found two equipment faults: a badly connected optical-fibre connector on the GPS timing link, which added about 73 ns of delay and made the flight time look shorter, and a master-clock oscillator running slightly fast, which pushed the other way. ICARUS measured light-speed-consistent arrival times in March 2012, and on 8 June 2012 OPERA and the other Gran Sasso experiments reported results consistent with c.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eδt = L\/c − t\u003csub\u003eν\u003c\/sub\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e(v − c)\/c ≈ c δt \/ L\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eδt: early arrival of the neutrinos relative to light (s)\u003c\/li\u003e\n\u003cli\u003eL: CERN-to-Gran Sasso baseline, about 730 km (m)\u003c\/li\u003e\n\u003cli\u003ec: speed of light, 299 792 458 m s⁻¹\u003c\/li\u003e\n\u003cli\u003et\u003csub\u003eν\u003c\/sub\u003e: measured neutrino time of flight (s)\u003c\/li\u003e\n\u003cli\u003ev: inferred neutrino speed (m s⁻¹)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWith L ≈ 730 km the light travel time is about 2.4 ms, so 60 ns is a 2.5 × 10⁻⁵ effect.
