Updates from the mission and the institute, published without an embargo and in chronological order.
Coronagraph door opens on schedule
First light from the white-light channel arrived eleven minutes after the command. Streamers are already resolved at 1.8 solar radii, better than the requirement.
Cruise phase trajectory correction completed
A 3.4 m/s burn refined the approach to the halo orbit and used sixty per cent less propellant than the allocation, extending the possible mission by four years.
Far-side magnetography validated against near-Earth data
Regions catalogued from L5 were compared with observations taken after solar rotation brought them into view. Field strength agreed within nine per cent.
Eleven states sign the forecast distribution accord
National grid and aviation authorities will receive the five-day bulletin directly from Davos from the first day of science operations.
Solar array deployment confirmed by telemetry
Both wings latched within four seconds of each other. Power margin at the end of commissioning stands at nineteen per cent above prediction.
SENTINELLE L5 lifts off from Kourou
Ariane 62 delivered the observatory into an Earth-escape trajectory 34 minutes after lift-off. First contact with Davos followed at 04:12 UTC.
