appropriate greeting

[Kwfine]

Hi,

I'd like to ask if it is appropriate to greet someone with "Good morning, XXX"
after 11:00 am.

Some of my lectures begin after 11:00 am,
and these are the expressions I use when I see my lecturers:
1. "Good morning, Prof. XXX"
2. "Good morning, Dr. XXX"

I dont think that it is usual to say "Good morning" to someone when it is around noon time,
but I just could't think of some better greetings.

Could you help please?

Kitty

'Good morning' is fine up right until noon, and you are forgiven if it is a bit after 12:00.
