Great video. Shows the vehicle all the way up to third stage ignition, when I presume the vehicle goes below the horizon. Lots of sparklers coming off the first stage.

Same clip of Launch of Epsilon Launch Vehicle (Flight Number 2) in stabilized mode.

Cool stars in the background.

Youtube's latest update wrecked about a 1/4th of users channels due to lack of testing.

Completion of Exploration of energization and Radiation in Geospace Arase(ERG)'s Critical Operations Phase

January 23, 2017 (JST)
National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

JAXA confirmed completion of the critical operations phase* of Arase(ERG), Exploration of energization and Radiation in Geospace. It results from a sequence of significant tasks that occurred as anticipated: perigee up maneuvers and extension of its wire antennae and masts.

 Arase is currently in good condition and is scheduled to enter into a two-month commissioning phase, then followed by a science operations phase.

 JAXA expresses its deepest appreciation for the indispensable contributions and support by all.

*Critical operations phase: period initiated at the separation of payload from a launch vehicle until payload’s stability is established. During this period, solar array paddles are deployed, and status of attitude control and tracking systems, and operations of ground tracking and control facility are ensured.
