Already, in the gathering dusk, a few of the stars are turning
on their lights.
Vega, the brightest one, is now dropping towards the west. Can
it be half
a year since I watched her April rising in the east? Low in the
Antares blinks a sad farwell to fall...

Oops! Attached is the APCC log.
PHD2 was running at the time. I assume that's what is sending guide pulses to
(1) Is there an automatic way that APCC can ignore the guide
pulses so that a flip can be executed?
(2) Or a button in APCC to force a flip?
(3) Or a recommended way to tell PHD2 to stop guide pulses
automatically during this time?

Actually, you only attached the ASCOM logs. To include APCC logs you must run
the APCC log zipper. Not everyone uses APCC so there is a separate ASCOM log
zipper, which is what you ran.
That said, I think I can still tell from the ASCOM logs why the flip was
stopped. It looks like something was sending the mount ASCOm pulse guide
commands (i.e., auto-guiding). An auto-guiding command will abort a slew.
