Interpreting Log - Dome communications

Hi,
I have these entries in one of my logs;

[03-01-17 05:24:27.071][DEBUG] [Sequence Thread] ASCOM Telescope: closing observatory shutter… Sequence Thread ASCOM Telescope: closing observatory shutter…
[03-01-17 05:24:27.179][DEBUG] [Sequence Thread] Dome: Closing Shutter
Sequence Thread Dome: Closing Shutter
[03-01-17 05:28:27.448][DEBUG] [Sequence Thread] ASCOM Observatory: Close shutter timeout! Sequence Thread ASCOM Observatory: Close shutter timeout!
[03-01-17 05:28:27.448][DEBUG] [Sequence Thread] ASCOM Telescope: parking observatory…
Sequence Thread ASCOM Telescope: parking observatory…

For the messages tagged “ASCOM Observatory” - are these for messages being passed through from the Dome/Ascom driver?

For instance, where it says “Close shutter timeout!” - is this SGP saying that a timeout error has occurred, or is this a message passed through from the dome driver, via ASCOM?

Thanks,
DaveNL
