Not a straight line path!

Yes, a good example of yaw steering/dog-leg maneuver, so as to achieve the desired sun-synchronous orbit when the launch azimuth for a direct flight would take the vehicle over another sovereign state's airspace (in this case, the Philippines), or put a drop zone onto land, or another sovereign state's territory.

(For the curious, "dog-leg" is an idiom in English.  We have dog-legged roads, dog-legged fairways on golf courses, etc.--slightly, but not severely bent.

Why dog-leg instead of cat-leg or horse-leg (or any appropriate mammal leg), I don't know.  One of the perks of being "man's best friend?")

Technically, the live coverage has started with a static shot of the H-IIA.

We're at T-15 minutes and counting. If you want to watch the Iridium-NEXT F4 mission's webcast, tune in to that one since it should start up any time now. That launch will occur 72 seconds after H-IIA leaves its pad.

From the Tanegashima Space Center in the Japanese island of Tanegashima, the Japan Aerospace Exploration Agency presents live coverage of the 37th launch of an H-IIA rocket, carrying the GCOM-C and SLATS satellites into two different sun-synchronous orbits.

No weather or technical issues seem to be in work at the present time.
