T-3 minutes.

Typically, for Ariane 5ES launches, the cryogenic swing-arms are not necessary since the second stage burns a mixture of monomethylhydrazine and dinitrogen tetroxide.

Pitch and roll programs have commenced and propulsion looks good in the main engine and SRBs.

And both SRBs have jettisoned. The main engine continuing to propel the Galileo satellites out of the atmosphere.

Still can see the launch vehicle from the naked eye without the use of telemetry.

Payload fairing has been jettisoned, exposing the four Galileo satellites to space.
