First stage engine shutdown: 00:01:48
Coping separation: 00:02:31
Separation of the first and second stage: 00:02:41

...
51 seconds of ballistic trajectory? I might know too little about rockets, but it surprises me.
Also, coping is another word for fairing?

Thanks for the timeline in any case!

Common for majority of multistage solid rocket boost stages.

It's to essentially let the first stage burn out all its propellant. If you separate the first and second stages early, the residual thrust can collide the discarded stage into the rest of the launch vehicle.

no, it is to allow the vehicle to gain altitude

Well, not in English!
But I think 'fairing' is indeed what is meant here.

Cause of scrub was connector trouble of the transportable Doppler radar at Uchinoura.

https://news.mynavi.jp/article/20211005-1995333/

This transportable Doppler radar is used both launch site (Uchinoura and Tanegashima). After the Epsilon F5 was launched, this transportable radar will be return to the Tanegashima launch site.

SCRUB!

The launch of the Epsilon PBS rocket has been cancelled due to winds at altitude. JAXA will give a new launch date when determined.

The rocket has already been returned to the maintenance building.

Successful F44 launch on October 26.

What is the minimum turn-around between launches using both orbital launch locations?
